The Green Bay Packers quarterback attributed his tight "blowout back" to to idling on the sideline during on his Milwaukee radio show Tuesday.
Rodgers threw six first-half touchdowns in the first half, tying the NFL record for most scoring passes in a half, before pulling himself from the game.
"My low back was actually hurting, said Rodgers. "I think I attributed that to standing around the entire time as the second half went on, not [from] anything that happened on the field…The guys took really good care of me on the field. I barely got touched all game, but my back actually got a little tight on the sideline…I forgot what a strain that can be to stand there and watch."
Rodgers had a shot at tying the league record for touchdowns in a game, but the Packers settled for a field goal on his final series before giving way to backup Matt Flynn.
