Penix (knee) may start Thursday's game against the Packers, Ian Rapoport of NFL Network reports.
Penix was ruled out for Week 2 on Friday, so Cooper Rush will start for the Falcons for the second time in as many games. However, Penix has been practicing fully for two weeks, and if he feels confident that he is ready to play on his surgically-repaired left knee, he could take over as Atlanta's starter in Week 3.
