Pittsford, N.Y. ? Buffalo Bills rookie Alvin Bowen sustained a severe right knee injury in practice Friday, and coach Dick Jauron expressed fear that the linebacker could miss the entire season.

“It doesn’t look like it’s going to be a good one, but we’ll wait and see, but anticipate that he’s not going to be playing much football this year,” Jauron said.

The Bills’ fifth-round pick out of Iowa State, Bowen was hurt during 7-on-7 drills while pursuing fullback Jonathan Evans, who had just caught a pass at the left sideline. When Bowen pulled up to avoid contact, his right cleat stuck in the turf, his knee buckled and he fell awkwardly to the ground yelling in pain.
