Rodgers suffered the non-contact injury moments before throwing a 4-yard touchdown pass to Randall Cobb in the second quarter. He remained down on the field for minutes before limping to the sideline as the crowd at Lambeau Field chanted, "MVP." Rodgers was then carted to the locker room for further evaluation.
Rodgers first injured the calf in the second series of last Sunday's win over the Buccaneers. He finished that game, but was limited in practice all week with what was classified as a calf strain.
The Packers clinch the NFC North and a first-round bye with a victory on Sunday. They may need every second of that time off with their most important player battling an injury that threatens to turn the playoff picture upside down.
