Kansas City Chiefs kicker Harrison Butker reported Friday that surgery on his left knee was done and was a success.

“Surgery went great! Thank you for the prayers,” Butker wrote on X.

The Chiefs announced Friday they had placed Butker, 29, on injured reserve and confirmed the signing of kicker Spencer Shrader, who had been on the New York Jets practice squad.

Eighth among NFL kickers in points with 75 this season, Butker connected on 18 of 20 field-goal attempts and 21 of 22 extra points. Both of the missed field goals were on tries beyond 50 yards.

Butker’s career 89.21 field-goal percentage ranks third in NFL history. He has won three Super Bowl titles with Kansas City.

Shrader has limited NFL experience.

A 25-year-old rookie from Notre Dame, Shrader connected on both of his field-goal attempts for the Jets last week at Arizona. He joined the Jets after being released by the Indianapolis Colts, who used Shrader in Week 1 for three successful PATs as the injury replacement for kicker Matt Gay.

The Chiefs (9-0), seeking their 16th consecutive win dating back to last season, visit the Buffalo Bills (8-2) on Sunday in a key AFC game.
