Gore (coach's decision) is inactive Sunday against the Cowboys, Adam Teicher of ESPN.com reports.
Gore won't be needed for now with the return of Clyde Edwards-Helaire (knee). Gore chipped in 10-plus snaps of offense each of the last three weeks, netting 20 carries for 80 yards and a touchdown. He'll likely need another injury to the Chiefs backfield to see the field again this season.
