Chiefs cornerback Javier Arenas and safety Jon McGraw are active for Sunday's game against the Denver Broncos after missing last week because of injuries.
Arenas, one of the top punt returners in the league, missed Kansas City's 31-3 loss to Miami with an ankle injury. McGraw missed the game with a shoulder injury.
Broncos safety Brian Dawkins is active against Kansas City despite an ailing thigh, and running back Willis McGahee is starting despite having surgery on his broken right hand a couple weeks ago. He ran for 163 yards and two touchdowns in his return last week, a 38-24 victory over Oakland.
Kansas City linebacker Demorrio Williams was ruled out for Sunday's game earlier this week because of a groin injury.
