The injury bug has bitten the Dallas Cowboys as eight-time Pro Bowl left tackle Tyron Smith suffered a major leg injury on Wednesday and will miss multiple months of the season, according to reports. 

"[Cowboys] standout LT Tyron Smith actually suffered an avulsion fracture of the knee, meaning the hamstring tendon that sits at the back of the knee pulled off the bone and he needs surgery, sources say," Ian Rapoport of NFL Network reported Thursday morning. "If he’s back at all, it’ll be December. A tough loss."

"I was in pass protect, and all the sudden, I see him on the ground," left guard Connor McGovern said Wednesday evening, according to The Dallas Morning News. "I didn’t even care where the ball was downfield. I instantly just went to him. You saw literally everyone on the offense, even defensive guys, running over there. When a guy like that goes down – it doesn’t even matter who it is, this team is so close. Everyone is trying to get over there and see if they’re all right and get them back up."
