The battle between the NFL's two leading rushers could be without one of its key participants this Sunday.
Star Kansas City Chiefs running back Kenneth Walker has been listed as questionable with a groin injury, ESPN's Ian Rapoport reported Friday.
The Chiefs (6-2) are set to take on the Atlanta Falcons (3-6) in a Week 10 matchup Sunday that features the NFL's No. 1 and 2 rushers in Bijan Robinson and Walker.
Robinson is entering Week 10 with 880 yards on 169 carries with five touchdowns, while Walker has ran for 872 yards on 159 attempts and seven scores.
