http://www.nfl.com/teams/story/IND/9591566 TERRE HAUTE, Ind. (Aug. 8, 2006) -- Three-time Pro Bowl selection Dwight Freeney joined the Indianapolis Colts ' rapidly expanding injury list, missing the morning practice after complaining of a sore shoulder. Colts coach Tony Dungy said Freeney, the 2004 NFL sacks leader, was held out for precautionary reasons and was expected to have an MRI. Dungy downplayed the severity of the injury, calling it a strain that occurred over time rather than something that could be pinpointed to a single play or hit. "It's something that's been bothering him, and it's our sense that he will be fine," Dungy said. "We just want to get it checked out. If it was a regular-season game, I'm sure he'd be out here practicing and playing." Dungy was uncertain which shoulder Freeney hurt or whether it was the one that required minor surgery last year. The mounting injuries, however, have forced Dungy and the Colts to make changes. Three of last season's starters -- defensive tackle Montae Reagor (knee) and safeties Bob Sanders (shoulder) and Mike Doss (calf) -- have missed at least one week of training camp. Another starter, former Pro Bowl defensive tackle Corey Simon (knee), has been out since Aug. 4. Starting linebackers Cato June, another Pro Bowl pick last season, and Gary Brackett have been limited to one practice each day and both were expected to miss Aug. 8's workout. If both linebackers are kept out, Indy would be missing seven of last season's starters. In all, 16 players missed the morning workout -- 12 of them dressed in blue defensive jerseys. The others included second-round draft pick Tim Jennings, a cornerback, who had offseason ankle surgery; defensive back Antoine Bethea (knee), a sixth-round pick in April; and backup quarterback Jim Sorgi (shoulder). Sanders, who made his first Pro Bowl last season, is on the physically-unable-to-perform list after having offseason surgery. He's hoping to start practicing next week. "I feel good right now," Sanders said. "The plan is to start doing one-a-days Tuesday." Freeney's absence, however, was the latest surprise. He practiced Aug. 7 and skipped the afternoon special teams-only session, as usual. But when Freeney arrived Aug. 8, he was wearing a baseball cap -- the Colts' symbol for players sitting out -- and occasionally clowned around with some of his injured teammates.
