Brackett

The Colts are waiting to get MRI results back to determine the severity of the injury.

The underrated IDP had been held out of training camp while rehabbing from offseason groin surgery. He’ll again start in the middle in 2006.

Brackett will participate in no more voluntary work. His agent believes Brackett will be ready for camp. The Colts have one of the longer lists of ailing players: QB Jim Sorgi (shoulder), WRs Marvin Harrison (hand/elbow) and Aaron Moorehead (back), Ss Bob Sanders (arm) and Mike Doss (shoulder), CBs Marlin Jackson (shoulder), Jason David (sports hernia), and Tim Jennings (ankle), and LBs Cato June (knee/sports hernia) and Keith O’Neil (shoulder).

He underwent surgery in early June. Because of his lack of name recognition, Brackett is one of the better IDP values around.

The Colts haven’t revealed the nature of Brackett’s injury, but it’s another unneeded blow to an Indianapolis run defense that has no prayer. Look for Pat Angerer to move from the strong side to middle linebacker, where he’ll start against the Browns. WLB Kavell Conner is expected to play Sunday, but is battling a bum left foot. Philip Wheeler figures to start at Sam. Peyton Hillis will be the best matchup-play running back in the NFL this week.

When asked how he felt on Monday, Brackett only responded “sore.” Not typically a cause for concern, but it is for a player who was limited to just one game last season as he dealt with groin and toe injuries. Brackett has appeared in more than 12 games just once since 2007.

Dallas Clark (foot) is active. With both Sims and Brackett out for the second straight week, the Colts are going to have almost no chance of slowing down Rashard Mendenhall this evening. Mike Pollak should get the start in place of Diem, who is nursing a hight-ankle sprain.

“At some point, maybe you revisit it,” Grigson said. “We’re confident with the decisions we made at the time. We still are and we’re moving forward.” The four Colts veterans have attracted little interest on the market and will likely have to wait until after the draft to catch on with a team.

Brackett, 32, had three years and $18.2 million left on his contract, none of which was guaranteed. The Colts are turning the page away from Cover 2 and toward a 3-4 defense. Brackett, a career Colt and former undrafted free agent, missed all but one game in 2011 due to a torn left rotator cuff. He will struggle to find more than a minimum deal on the open market. Brackett was the Colts’ starting middle linebacker for six seasons. He racked up at least 90 tackles five times.
