(WNFL) - E-S-P-N said Aaron Rodgers had a small fracture in his collarbone early in last night's Green Bay Packers' 27-20 home loss to Chicago. The network's Adam Schefter said the word from N-F-L 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-point-four passer rating in relief of Rodgers last night 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 signal-caller. 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-and-3, all leading the N-F-C North Division.
