The Kansas City Chiefs could be missing a key player when they face the Baltimore Ravens in the AFC Championship Game on Sunday.

Chiefs offensive lineman Joe Thuney left his team’s Divisional Round win over the Buffalo Bills at Highmark Stadium with a chest injury. He underwent an MRI after the game that revealed he has a strained pectoral muscle.

According to ESPN’s Adam Schefter, Thuney is facing an uphill battle to play against the Ravens but is “going to work like crazy” to try to suit up.

Thuney has made the Pro Bowl in each of the last two seasons. The right guard was also recently named a first-team All-Pro for the first time in his career.

Thuney, who won two Super Bowls when he was with the New England Patriots and a third last year with the Chiefs, has played through significant injuries in the past. It would not be a shock if he does so again in Baltimore, but he is clearly not going to be at full strength even if he plays.
