Aaron Kampman's status for Sunday's game is known.
The news Friday wasn't as bad for Terrance Knighton, but the defensive tackle's status likely won't be known until Sunday.
Kampman, the Jaguars' 10-year veteran defensive end, will miss Sunday's game against Indianapolis with a hamstring injury, Jaguars Head Coach Jack Del Rio said Friday afternoon, while Knighton – a third-year defensive tackle – is questionable with an ankle injury.
Kampman missed the first five games of the season with a knee injury.
"It's unfortunate that the year hasn't gone the way he (Kampman) would like," Del Rio said Friday afternoon as the Jaguars (2-6) prepared to play the Colts (0-9) at Lucas Oil Stadium in downtown Indianapolis Sunday at 1 p.m.
"He just hasn't been able to get over the hump."
Kampman, who signed with the Jaguars as a free agent in the 2010 off-season after sustaining a season-ending anterior cruciate ligament injury in Green Bay in 2009, sustained a torn ACL in the other knee midway through last season.
He missed the final eight games last season, then played in the preseason finale this year before missing the first five games of the season.
He then played the final three games before the bye, registering two quarterback pressures, but Del Rio said Kampman had a setback over the bye weekend "doing a little extra."
"At this point, that's not where the focus is," Del Rio said. "Our focus is on taking the guys who are ready to go up to Indy to win this ball game. I know he's disappointed and certainly we'd love to have him available."
Knighton, a starter in all eight games this season, sustained an ankle injury in the Jaguars' final game before the bye – a 24-14 loss at Houston – and was limited in practice Wednesday and Thursday before not practicing Friday. Knighton saw a specialist about the ankle Friday.
"It's just a little bone bruise," Knighton said. "It's not too bad. We're just going to be careful with it and see how it feels Sunday. It feels fine walking and doing certain things, but taking on blocks, it gets a little twisted at times. We'll give it a little more rest these next two days, get a little more treatment and hopefully, I'll be able to go full speed by 1 o'clock (Sunday)."
Knighton and Del Rio said there was no concern about Knighton's injury being more several than originally thought.
"All the bad stuff has been ruled out," Del Rio said.
Del Rio said a decision on Knighton will be made close to game time.
Also for the Jaguars:
*Aside from Kampman, fullback Brock Bolen (calf) and offensive tackle/guard Eben Britton (back) have been ruled out for Sunday. Neither Bolen nor Britton practiced this week.
*Knighton and wide receiver Brian Robiskie have been listed as questionable for Sunday. Robiskie was limited in practice the last two days with a hamstring injury.
*Defensive end John Chick (abdomen), safety Courtney Greene (hamstring) and wide receiver Cecil Shorts (hamstring) have been listed as probable. All three players practiced full after missing the Houston game just before the bye.
*Del Rio said the Jaguars' week of preparation was focused and productive, as has been the case all season. "I've said repeatedly that this group of men has remained very focused," Del Rio said. "The effort and the energy they put forth every day has been good. You couldn't look at practice and see the record. It just doesn't reflect the record. The record is what it is, but we get a chance to go up there and get the second half of the season started. We understand the urgency of it."
