Green Bay Packers quarterback Aaron Rodgers cautioned Friday that a lot of things have to go right for him to return in 2017.

Rodgers told fans to “temper expectations” and any return would come down to how well his broken collarbone heals.

“It’s going to come down to the bone healing. That’s the most important thing,” Rodgers said Friday, via Mike Spofford of the Packers’ official website. “There won’t be a decision made until that bone is healed, so it’s not even a conversation if it’s not where it needs to be.”

Rodgers has no concerns over a long-term recovery, but he won’t force the issue if the bone is not healing quickly enough.
