Kenneth Walker III out against NFL rushing leader Bijan Robinson’s Falcons, Patrick Mahomes off injury report

Kenneth Walker III will miss Kansas City’s game against Atlanta on Sunday after being ruled out with a groin injury. His absence removes a key threat from a matchup between the NFL’s two leading rushers and puts rookie Emmett Johnson in line for more work.

Atlanta’s Bijan Robinson has 880 rushing yards, eight more than Walker’s 872. Johnson has run for 111 yards and a touchdown and caught 14 passes for 237 yards and another score this season. Patrick Mahomes has no injury designation after practising fully all week, while defensive tackle Chris Jones is expected to join the team in Atlanta.
