INDIANAPOLIS -- Colts linebacker Tyjuan Hagler was cleared to resume a full practice schedule and could be back in the lineup for Indianapolis' AFC South matchup with Jacksonville.
Hagler has missed four games after suffering a pinched nerve in his neck against Carolina on Oct. 28, and expects to play this weekend after practicing Wednesday and Thursday.
Colts coach Tony Dungy, however, is taking a wait-and-see attitude.
"He's getting better," Dungy acknowledged. "It's been tough. We've had a few guys like that, that have been itching to get back and haven't been able to."
Marvin Harrison is one of them. The veteran wide receiver hasn't played since the Colts and Jaguars met on Oct. 22 due to a bruised left knee, and might not be available Sunday. He has been sidelined for six of Indianapolis' last seven games and hasn't gone through a full practice in more than a month.
"I thought that he's going to need a couple of good practice days to really be ready to go," Dungy said. "So we'll see what happens."
Meanwhile, cornerback Dante Hughes (shoulder) was placed on injured reserve and is done for the season. The Colts signed former Cincinnati and Tampa Bay cornerback Keiwan Ratliff to replace him, and signed second-year cornerback Darrell Hunter to the practice squad.
Also sitting out Thursday's practice were: offensive tackles Ryan Diem (ankle) and Daniel Federkeil (concussion); middle linebacker Gary Brackett (illness); weak side linebacker Freddy Keiaho (illness); and safety Bob Sanders (team decision).
Brackett, Keiaho and Sanders are all expected to play Sunday. The status of Harrison and Diem will be updated before the game.
Offensive tackles Tony Ugoh (neck) and Charlie Johnson (hamstring) and cornerback Tim Jennings (upper leg) practiced Thursday. A final decision on their availability will likely be made after Saturday's workout.
