Green Bay Packers nose tackle B.J. Raji has a torn biceps, according to NFL Network.
Raji got hurt during the first quarter of the Packers' game Friday night.
Raji was replaced by Josh Boyd.
The Packers could also go with Ryan Pickett, who's a free agent.
Following the game, Packers coach Mike McCarthy said Raji was "pretty confident" about the injury.
If it's not fully torn, Raji could possibly return at some point this season.
