The 2014 season is currently in doubt for Packers nose tackle B.J. Raji, who injured his arm against the Raiders on Friday. According to NFL.com, Raji has suffered a torn biceps.

The Packers fear that the injury is 'season-ending,' according to the Milwaukee Journal Sentinel.

Following the Packers 31-21 win, Green Bay coach Mike McCarthy said Raji was confident that the injury wasn't serious, but McCarthy did add that his nose tackle would undergo tests on Saturday.

It's not clear when Raji was injured during Friday's game. The ninth overall pick in the 2009 NFL Draft only played in two series against the Raiders before spending the rest of the night on the sideline.
