Chiefs Rule Walker Out Against Falcons

The Chiefs ruled out running back Kenneth Walker III for Sunday’s game against the Falcons after he tweaked his groin in practice, opting to give him a week to recover rather than risk worsening the injury. Walker has rushed for 872 yards and seven touchdowns in eight games; rookie Emmett Johnson is expected to lead the backfield, while Jaydn Ott is questionable and Nate Carter was added from the practice squad. Patriots running back TreVeyon Henderson was also ruled out of Sunday’s game against Detroit in Munich after an illness involving unexplained neurological symptoms and hospitalization; coach Mike Vrabel said there is no timetable for his return, and the Week 11 bye means Nov. 29 is his earliest possible return. Rhamondre Stevenson is dealing with a knee injury, leaving Corey Kiner and Lan Larison among New England’s backfield options; Detroit listed Amon-Ra St. Brown and Sione Vaki as questionable.
