ORCHARD PARK, N.Y. -- Derek Fine's season is over after the Buffalo Bills placed the veteran tight end on injured reserve because of a knee injury.
Klopfenstein, a 2006 second-round draft pick, spent three seasons with the St. Louis Rams before being released in September. He has 33 catches for 386 yards and two touchdowns in 48 career games.
Buffalo also shuffled its practice squad by signing offensive lineman Christian Gaddis and placing wide receiver C.J. Hawthorne on the injured list.
