"I didn't pass my physical," said Rodgers, who declined to get into specifics but later mentioned injuries to his ankle, calf and knee.
"I've been on the injury report at various times during the season with my ankle (that) was hurting me," he said. "I will say that my ankle has definitely been a problem. During the season, I've been on the injury report at least once with that."
Rodgers also said his calf has bothered him for several weeks and that he had received an injection in his knee.
Rodgers made waves last year when he criticized the quality of play at the Pro Bowl. This year's game is scheduled for Jan. 27.
