[Kansas City.com] Chiefs quarterback Matt Cassel could miss the remainder of the season after sustaining what coach Todd Haley is calling a “significant” injury to his throwing hand.

Cassel hurt his right hand near the end of the Chiefs’ 17-10 loss to Denver on Sunday.

Haley refused to say whether the team would put the former Pro Bowl quarterback on injured reserve. But he did say “it’s a possibility” when asked whether he’d miss the rest of the season.

Cassel will “probably have to have surgery at some time to get it corrected,” Haley said. “It’s a difficult injury.”

Tyler Palko is expected to start Monday night at New England. The journeyman backup was 5 of 6 for 47 yards in Kansas City’s final offensive series against Denver.
