UNDATED (WHBL) - ESPN says Aaron Rodgers suffered a small fracture in his collarbone early in Monday night's Green Bay Packers' 27-20 home loss to Chicago. The network's Adam Schefter said the word from NFL sources is that Rodgers could miss around three weeks. There's been no confirmation from the Packers, who say they'll wait for more tests today to determine Rodgers' injury and status. The Pack said its franchise quarterback suffered an injury to his non-throwing shoulder when Rodgers was hit by Bears' linebacker Shea McClellin. It happened on the final offensive play of the Packers' opening drive. 33-year-old Seneca Wallace had a 53.4 passer rating in relief of Rodgers with 114 passing yards and a pick. He was also sacked four times, as Green Bay only converted one of eight third downs with Wallace in the game. Coach Mike McCarthy said the Packers need to do a better job in its passing game, and Wallace will benefit from a week of practice as the number one quarterback. The Packers have a short week of preparation in getting ready for Sunday's home matchup against Philadelphia. If the Packers decide that Wallace is not the answer, they could promote ex-Badger Scott Tolzien from the practice squad. Also, former Packer Matt Flynn was cut by Buffalo - his third team this season. Green Bay, Chicago, and Detroit are all 5-3 on the season - tied for first place in the NFC North.
