Buffalo Bills wide receiver Stevie Johnson missed practice Thursday because of a sore groin that has been bothering him for about a month.
"Stevie's been having a nagging groin for a month, so we just gave him a rest today," Gailey said following Thursday's practice, via the Buffalo News.
Johnson told reporters he expects to practice Friday.
Johnson appeared to tweak the injury in a position drill Wednesday during the portion that reporters were able to watch. He took a few repetitions off before returning.
