Cam Newton's season could be over. 

The Panthers quarterback saw a specialist this week to evaluate the progress of his foot injury, according to NFL's Ian Rapoport. The doctors didn't recommend surgery, but he will need "several weeks" to rest and rehab his foot. 

Rapoport claims that the diagnosis left Cam "frustrated" as he expected to be ready to take the field. With the season speeding by, it's likely that the Panthers will put Newton on injury reserve, ending his season.

Newton first injured his foot during the Panthers' third preseason game against the New England Patriots. Initially, Cam was said to have a mild foot sprain that wouldn't prevent him from missing any games. He ended up re-aggravating the injury during Week 2's contest against the Tampa Bay Buccaneers. After a series of tests, doctors concluded that Cam had a Lisfranc injury. He has been sidelined since Week 3.
