GREEN BAY, Wis. -

According to multiple reports, BJ Raji tore his right biceps during Friday's 31-21 win over Oakland at Lambeau Field. The injury was first reported by NFL.com. 

According to the report, Raji is expected to miss the entire 2014 season.

Raji left the game in the first half and was spotted with his arm wrapped in an ice bag. In the second half, Raji took off his uniform and wore street clothes on the sideline. 

The team has yet to make an official announcement. 

The loss leaves a hole in the middle of the defensive line, as Raji was set to be the starting nose guard.

One option for a replacement could be Ryan Pickett, whose contract expired in the off-season and was not re-signed by the Packers. Pickett played for the Packers from 2006 to 2013. 

The Packers open the regular season Thursday, Sept. 4 at Seattle. 

An AP report Sunday said Raji had his right arm in a sling at Sunday's practice.
