The stand-in for Butker this weekend (and beyond, for now) is Spencer Shrader, an undrafted rookie who has appeared in two NFL games this season. In Week 1, he made all three extra points for the Colts as a replacement for Indy’s starter; then he returned to the practice squad and was later released.

Butker gave a social media update on Friday after it was revealed on Thursday that he would require surgery to fix his injured left knee.

The Kansas City Chiefs have remained undefeated entering Week 11 despite losing several key players in the early season. The Chiefs are set to lose another important player for several games.
