Stevie Johnson practiced Friday, but the Buffalo Bills listed the wide receiver as questionable for Sunday's game against the St. Louis Rams.
Johnson injured his hamstring against the Jacksonville Jaguars last week and couldn't practice Wednesday. He returned to the field Thursday.
"He was better (Friday) than he was (Thursday)," Bills coach Chan Gailey said to WGR-AM in Buffalo. "We're going to talk about it and see how he feels (Saturday) morning before we make a full decision."
Johnson leads the Bills with 55 catches for 705 yards and five touchdowns this season.
