Aaron Rodgers has been placed back on injured reserve by the Green Bay Packers.
The quarterback missed seven games after breaking his collarbone in week six of the season against the Minnesota Vikings.
Rodgers returned for the Packers' 24-31 defeat to the Carolina Panthers on Sunday.
Atlanta's win against Tampa Bay on Monday Night Football ended Green Bay's eight-year run of consecutive post-season appearances.
The two-time NFL MVP showed glimpses of being back to his best at the weekend when he threw a 13-yard pass to Davante Adams that tied the game at 7-7 but was forced into three interceptions and was ultimately outdone by his counterpart Cam Newton.
"Aaron Rodgers is sore, rightfully so," Packers coach Mike McCarthy told the Milwaukee Journal Sentinel on Monday.
"He was hit too many times, took two big hits. So we're working through that."
Brett Hundley will start for Green Bay in Saturday's home game against the Vikings with new signing Joe Callahan as his backup.
The Packers have also released fullback Joe Kerridge from the active roster and quarterback Jerod Evans from the practice squad.
