Source: Cowboys activating Pro Bowl LG Tyler Smith (thumb) from IR

The Dallas Cowboys are activating Pro Bowl left guard Tyler Smith from injured reserve to play Thursday night against the Tampa Bay Buccaneers, a source told NFL Network's Ian Rapoport.

This will be the season debut for Smith, who has been on injured reserve after having surgery last month on his left thumb.

The Cowboys opened Smith's practice window Monday.

Smith said Monday he is wearing a cast on his thumb for extra protection, and his conditioning is fine thanks to the work he has done with the athletic training and strength staffs.
