Tennessee Titans quarterback Vince Young didn't practice Friday and is listed as questionable for Sunday's game against the Philadelphia Eagles.
Jeff Fisher didn't rule him out but it's going to take a very good pre-game warmup for Young to play.
"He did some things inside, and that's progress for us," Fisher said.
He suffered an ankle and knee injury Monday night. Kerry Collins has taken all the snaps.
With it being a short week because of the Monday night game, Collins is the leading candidate to be the starter.
"I'm ready to go. I've a good week of practice and I'm entirely comfortable with what we're doing game-plan wise," Collins said.
Tight end Bo Scaife (groin) and defensive tackle Tony Brown (knee) didn't practice Friday and are listed as questionable.
Cornerback Jason McCourty (forearm) and receiver Justin Gage (hamstring) are questionable, but they did some work in practice Friday and have a chance to play.
