Seattle Seahawks safety Earl Thomas is thinking about retiring after reportedly cracking his tibia Sunday night against the Carolina Panthers.

Thomas, 27, left Sunday's game on a cart after taking a hit when he was attempting to intercept a pass from Cam Newton. 

According to NFL Network's Ian Rapoport, Thomas cracked his tibia and is out indefinitely.

From the locker room, Thomas sent out a tweet questioning his future in the NFL.

Thomas, a Texas product, is a seven-year veteran with the Seahawks. He's a five-time Pro Bowler and won a Super Bowl with Seattle in 2014.
