Carolina Panthers quarterback Cam Newton underwent surgery on Wednesday afternoon to repair ligament damage in his left ankle.
The full recovery process is four months, which would take Newton until the start of training camp. However, he could be freed to throw on a limited basis before then.
"Dr. (Robert) Anderson did not find anything unexpected in the procedure and the surgery went well," Carolina head athletic trainer Ryan Vermillion said in a statement.
This is the second red flag in Newton's offseason, the other being the Panthers' woeful WR situation. They cut Steve L Smith and let both Brandon LaFell and Ted Ginn walk as well.
