Bills place TE Fine on IR; sign Klopfenstein

ORCHARD PARK, N.Y. -- Bills tight end Derek Fine's season is over after being placed on injured reserve because of a knee injury.

Fine will be replaced by Joe Klopfenstein, who was signed in free agency.

The moves came Wednesday, a day after defensive coordinator Perry Fewell was promoted to interim head coach following Dick Jauron's dismissal. Buffalo (3-6) plays at Jacksonville on Sunday.

Klopfenstein, a 2006 second-round draft pick, spent three seasons with St. Louis before being released in September. At 6-foot-5 and 252 pounds, he had 33 catches for 386 yards and two scores in 48 career games.

Buffalo shuffled its practice squad by signing offensive lineman Christian Gaddis and placing receiver C.J. Hawthorne on Practice Squad, Injured.
