http://www.usatoday.com/story/sport.../23/bj-raji-biceps-injury-green-bay/14498309/ The Green Bay Packers' worst fears have been realized. Packers defensive lineman B.J. Raji will be lost for the entire 2014 season because of a torn right biceps injury sustained in the first quarter of Friday night's 31-21 win over Oakland, a person familiar with the injury confirmed to Press-Gazette Media. ESPNand NFL Networkfirst reported the injury's season-ending severity. Packers coach Mike McCarthy said after the game Raji was "pretty confident" about the initial diagnosis for the arm injury, but tests Saturday indicated more significant damage than first thought. Raji played only seven snaps against the Raiders before exiting. He stayed on the sideline for the rest of the game with a sleeve over his right arm. Afterward, he was seen in the locker room with a bag of ice on his right biceps. Raiders-Packers takeaways: Eddie Lacy ready to roll again Raji played only seven snaps against the Raiders before exiting. He remained on the sideline with a sleeve over his right arm. Afterward, he was seen in the locker room with a bag of ice on his shoulder. The loss of Raji would deal a significant blow to the Packers' remade defensive line. Although he's coming off a disappointing 2013 season, Raji has looked more explosive since moving from defensive end back to nose tackle. Second-year defensive lineman Josh Boyd stepped in at nose tackle in place of Raji against the Raiders. Undrafted rookie Mike Pennel, who's been making a strong argument for a roster spot, also received extensive work inside. The Packers signed former Minnesota defensive lineman Letroy Guion to a one-year deal in March to spell Raji, but he's missed all of training camp with a torn hamstring and could be headed to the physically unable to perform list. The Packers could now reach out to 34-year-old Ryan Pickett, who remains a free agent. Weston Hodkiewicz writes for the Green Bay Press Gazette.
