NASHVILLE, Tenn. - Vince Young is day-to-day after tests show only a mild sprained left knee and ankle, and coach Jeff Fisher said the Tennessee Titans quarterback could play against the Eagles Sunday even if he misses a couple practices.

"If you look at . . . what happened in the game, I could stand up here and say that he's lucky," Fisher said yesterday. "He's got just a mild knee sprain, and he's got an ankle sprain. He's sore. As he said, he's a quick healer, and we'll just go with him day to day."

Young thought his season might have ended when he was hurt Monday night in a 30-3 win at Jacksonville. He was pulled down after recovering a fumbled snap with his left leg twisting underneath him. He was able to walk off the field, and he could be seen making the sign of the cross and praying on the sideline.

Fisher said Young could have played if needed, taking snaps out of the shotgun only because of his limited mobility.

If Young can't go against the Eagles, veteran Kerry Collins will start.

Young is off to his best start, completing 61.4 percent of his passes with seven touchdowns and only two interceptions. He ranks fourth in the AFC with a passer rating of 98.8.
