Tennessee Titans quarterback Vince Young is questionable for Sunday's game against the St. Louis Rams after re-aggravating his sore right knee.
Young watched Kerry Collins take all the first-team practice repetitions Friday, one day after tweaking the knee. Young originally was hurt during last Sunday's 27-17 road loss to the Indianapolis Colts, though tests on the knee came back fine.
"He didn't practice today," said Titans coach Jeff Fisher, who added that Young missing practice "will not have anything to do with whether or not he plays. He understands the game plan and got at least half of the preparation."
Young told the The Tennesseanon Friday that he would play.
Titans running back Chris Johnson returned to practice and is listed as probable this week, as is wide receiver Kenny Britt, who also fully participated in practice after being added to the injury report Thursday with a back injury.
Fullback Ahmard Hall (ankle), tight end Jared Cook (concussion) and wide receiver Nate Washington (ankle) also both practiced fully and are listed as questionable.
Linebackers David Thornton (rest) and Colin Allred (hamstring) are questionable after being limited in practice Friday.
Note: The Titans promoted DE Eric Bakhtieri from the practice squad to the active roster Friday and placed DT Jason Jones on season-ending injured reserve. Jones had shoulder surgery Wednesday.
