The injury occurred while Beason was attempting to chase down Arizona tight end Jeff King on a 48-yard touchdown reception in the third quarter. Beason collapsed to the ground and was carted off to the locker room.
Teammates, perhaps bracing for the worst, spoke of Beason with respect after the game.
"I'm just happy and honored to be on this team because we had guys out there that were blowing out tires to fight," wide receiver Steve Smith said of Beason. "It doesn't get any better than that. You don't get guys in the locker room like that. It rarely comes and when you have a guy who does that you surely miss him, but he's admirable for his effort and I'm honored and pleased to be his teammate."
Beason has had issues with his left leg in the last several months leading up to Sunday's season opener. The three-time Pro Bowler was originally diagnosed with Achilles tendinitis, which was later revealed to be inflammation of the bone. Beason then had three screws inserted in his foot on Aug. 22.
