NASHVILLE, Tenn. -- Tennessee quarterback Vince Young will be day to day this week after reinjuring his right quadriceps muscle. His status for Sunday's AFC wild-card game with San Diego could be in question.

"I can't really say right now if Vince is going to play this week," coach Jeff Fisher said Monday. "I have a good feeling he'll be back on the practice field, and we'll see how he goes."

Young missed a start Oct. 21 at Houston after straining his right quadriceps in Tampa on Oct. 14. He said he aggravated the muscle in the first half of Sunday night's 16-10 win at Indianapolis and tweaked it further in the third quarter.

He limped to the sideline a play later, was stretched by trainers and even went to the locker room for a few minutes. He did not return to the game, and backup Kerry Collins led the Titans to three straight field goals and the victory that clinched a playoff berth.

Fisher said Young was very excited about his play against the Colts, the win and the chance to play in a post-season game. Young was 14-of-18 for 157 yards when he left, and Fisher said Young could have returned to the game.

But Fisher said he isn't thinking of starting Collins, who was 10-of-13 for 106 yards, at San Diego.

The coach said they will evaluate Young through the week and is optimistic Young could practice. Fisher said he would give a complete injury report Wednesday and that Young was not among a few Titans having tests Monday.

Running back LenDale White, listed last week on the injury report because of a sore knee, split carries late against the Colts with Chris Henry. Chris Brown, who lost a fumble inside inside the Colts 10 in the second quarter, had his back tighten up.

Right guard Benji Olsen left the game in the second half and was replaced by Daniel Loper, while cornerback Nick Harper was replaced by Reynaldo Hill. Center Kevin Mawae missed his second straight game with a calf injury.

Young has struggled against 3-4 defences like San Diego's. Asked if Young needed to practice to play, Fisher said he wouldn't get into hypotheticals.

"We'll just take it one day at a time. He would benefit from practice, yes. But he's also played them several weeks ago," Fisher said.

Young threw for 121 yards and was intercepted twice Dec. 9 in a 23-17 overtime loss to the Chargers in Nashville. He also was sacked once and ran only twice for 2 yards.
