TORONTO -- Toronto FC will be without star striker Jermain Defoe and defensive lynchpin Steven Caldwell for Saturdays game against the Columbus Crew. Muggsy Bogues Jersey . Defoe, who has scored all three of Torontos goals this season, has been sidelined by a slight hamstring strain while Caldwell must serve a suspension. And the injury list could be longer with midfielder Jonathan Osorio facing a second week out with his own hamstring issue. Manager Ryan Nelsen says Defoe, who had a scan Tuesday after leaving Saturdays game in Salt Lake City early, will be out "for the short-term." "Not a major thing but definitely unavailable this weekend," he said. The 31-year-old England striker was substituted in the 61st minute Saturday favouring the back of his left thigh as he went to the dressing room. Caldwell was suspended one game and fined an undisclosed amount Wednesday for what MLS called "serious foul play that endangers the safety of an opponent." The hard-nosed Scottish centre back -- TFCs captain -- was yellow-carded for a studs-up tackle on midfielder Ned Grabavoy in the 3-0 loss to Real Salt Lake. Toronto had hoped to avoid a ban, arguing that the referee had seen the incident and decided on the appropriate punishment. But the leagues disciplinary committee disagreed. While Caldwell insisted he was just trying to win the ball, it was an ugly challenge that could have merited a straight red card, which carries with it a minimum one-game suspension. Caldwell is the second Toronto FC player to receive supplemental discipline. Brazilian midfielder Jackson missed the Salt Lake game after getting a one-game ban for an elbow thrown away from the ball in a 1-0 win over D.C. United. The latest suspension is especially worrying because Doneil Henry, Caldwells partner in central defence, has not trained this week because of a jarred knee suffered in Salt Lake City. "There could be a few guys unavailable," said Nelsen, who has repeatedly noted that the teams that succeed in MLS are the ones with the depth to cover such absences. The Toronto manager, who brought in as many as eight new starters in the off-season, is on the lookout for such reserve talent. "They normally play under the radar, they dont get any publicity or anything like that. Theyre the most valuable players on MLS teams and Toronto hasnt had those type of guys. Were trying to build them, were trying to get them, were trying to bring them (in), were trying to develop them ourselves. "For me, (the time) well get very, very, very good is when we can have a number of those guys who throw out seven of 10 (performances) every week." Goalkeeper Julio Cesar, who also took a knock to the knee on the weekend, was back in training Wednesday. And Toronto has Jackson back from suspension. Nelsen declined to say who will partner Brazilian striker Gilberto on Saturday against the unbeaten Crew (3-0-0). Nelsen played Canadian international Dwayne De Rosario up front with Defoe in the opening game of the season in Seattle when Gilberto was not ready. He pointed to De Rosario, Jackson, Andrew Wiedeman and newly signed Issey Nakajima-Farran as possible options. There was no "woe is me" from Nelsen. "Jermains come in and done really well obviously. But he got a slight strain and we move on. Thats life." On the backline, Nelsen has Gale Agbossoumonde and rookie Nick Hagglund at his disposal. American Justin Morrow could also move in from the left flank. Reserve fullback Ashtone Morgan is also dealing with a sore hip. Nelsen has spoken at length the last two days on the leagues supplemental discipline, arguing that it can undermine referees when the league rules on incidents that the on-field officials have already ruled on. "I dont know why the league needs to get involved, to tell you the truth," he said Wednesday. Still he seemed to want to have his cake and eat it too when, awaiting word last week on the Jackson suspension, he argued that Real Salt Lake forward Alvaro Saborio deserved a ban for his foul on A.J. DeLaGarza of the Los Angeles Galaxy the previous week. "That could have broken his leg," Nelsen said at the time of the Saborio challenge. "So if Jackson gets suspended, then youd like to hope that a guy whos nearly broken a guys leg is probably going to get suspended as well. "But I dont know, you never know. I dont make those rules." Nelsen was no doubt aware that RSL was already facing a glut of injuries at forward. His argument is that such supplemental discipline sets a precedent, effectively prompting all clubs to seek justice. "So do we slow down all elbows that were hit on Jackson before he did one or the elbow on Steven before that tackle?" he asked. "Its a slippery slope isnt it when you start overturning referees and taking away the human element of it, then every single team will have cases every single week." Unlike the NHL, MLS players are still paid while suspended. Also Wednesday, the leagues disciplinary committee fined Colorado Rapids defender Drew Moor an undisclosed amount for swinging his arm at the back of Sporting Kansas City forward Claudio Bielers head. According to the league, the disciplinary committees mission statement is "to preserve the integrity and reputation of the game and Major League Soccer, and to assist in ensuring player safety." The committee can take further action when the referee has seen or ruled on an incident on the field, if there is unanimous opinion that the play deserved a red card or was of "an egregious or reckless nature, such that the committee must act to protect player safety or the integrity of the game." Al Jefferson Jersey . -- Kansas City Royals first baseman Eric Hosmer will be out three to six weeks with a stress fracture of the third finger of his right hand. Anthony Mason Jersey .ca NHL Power Rankings, ahead of the Chicago Blackhawks, St. Louis Blues and Anaheim Ducks. Moving up, from 10 to seven this week, the Pittsburgh Penguins have won seven straight despite a depleted lineup.Roy Oswalt retired from baseball on Tuesday after winning 163 games and making three All-Star teams in 13 major league seasons. The pitchers agent, Bob Garber, confirmed the decision and said Oswalt would go to work for his agency, RMG Baseball. Oswalt will be vice-president of baseball operations. "Roy is now going to be representing players with me," Garber said Tuesday night. "Hes now an agent." The 36-year-old right-hander had a 163-102 career record with a 3.36 ERA. Oswalt won 20 games in consecutive seasons (2004-05) with the Houston Astros and was the 2005 NL championship series MVP. He pitched more than 200 innings seven times but was hampered by injuries in recent years. "He was a tremendous competitor," Giants right-hander Matt Cain said. "He was one of the guys I always loved to watch pitch. I remember facing him for the first time and I knew if I gave up more than a couple runs that it wasnt going to be a good day for us. He went about his business every fifth day like a true pro." Oswalt got hurt with Houston on June 11, 2003, when he and five other pitchers combined to no-hit the New York Yankees in an 8-0 victory in the Bronx. It was the only six-pitcher no-hitter until Seattle did the same thing against the Dodgers on June 8, 2012. Oswalt strained his right groin and left in the second. He looked toward catcher Brad Ausmus after his second pitch of the inning, his 23rd of the game, and immediately was replaced. The Yankees had gone 6,980 games -- the longest streak in major league history -- without being no-hit, since Hoyt Wilhelms 1-0 victory for Baltimore on Seppt. Gerald Wallace Jersey. 20, 1958. Oswalt was 0-6 with an 8.63 ERA in nine outings and six starts for Colorado last year. He signed a minor league deal with the Rockies in May 2013 and missed time with a strained left hamstring. Texas Rangers manager Ron Washington was thrilled to acquire Oswalt in the middle of the 2012 season, when he went 4-3 with a 5.80 ERA in 17 appearances with nine starts. He joined the Rangers on June 22, 2012, but didnt know if the team just planned to trade him away. Washington often said Oswalt "has been a pro" in handling a tough, unclear situation that called for him to be used primarily out of the bullpen. That was after Oswalt spent two stints on the disabled list during 2011 with Philadelphia because of lower back inflammation. He went 9-10 with a 3.69 ERA in 23 starts for the Phillies that year, and his 139 innings were his fewest since 2003. He didnt go more than 59 innings in his last two years. A 23rd-round pick by Houston in the 1996 amateur draft, Oswalt pitched his first nine-plus seasons for the Astros (2001-10) and then played for Philadelphia (2010-11), Texas (2012) and the Rockies (2013). On Aug. 25, 2010, Oswalt became the first Phillies pitcher to play a position in the field in 39 years after Ryan Howard was ejected in the 14th inning of a 4-2, 16-inning home loss to the Astros. With the Phillies out of position players, Oswalt went to left field and Raul Ibanez took over at first for Howard. Oswalt drew a rousing ovation from the crowd when he caught a routine fly ball. He was the first Philadelphia pitcher to play a position since Bill Wilson on Aug. 6, 1971. ' ' '
