NFL Network’s Ian Rapoport reports Chiefs G Trey Smith (ankle) won’t play in Week 13 against the Cowboys.

Smith sustained two sprains on the same ankle in the team’s Week 12 game against the Colts and did not practice Tuesday ahead of KC’s Thanksgiving matchup with the Cowboys. It’s a blow to the Chiefs offense, as Pro Football Focus grades Smith as the NFL’s tenth best pass-blocking guard this season. The Dallas front seven has been much improved over the past three weeks.
