The Kansas City Chiefs are leading the Oakland Raiders, 21-3, as the two teams head into the locker room for halftime at Arrowhead Stadium.

Chiefs' quarterback Patrick Mahomes completed 10-of-17 passes for 148 yards and a touchdown in the half, putting the Chiefs on the board early with a 67-yard scoring strike to wide receiver Tyreek Hill.

It marked Hill's 12th touchdown of the year and pushed the speedy wide out into the top spot in franchise history for receiving yards during a single season, passing the mark held by Derrick Alexander.

Kansas City was back in the end zone a short while later as safety Daniel Sorensen picked off Raiders' quarterback Derek Carr and brought it back 54 yards for a touchdown. It was one of four Chiefs' takeaways on the afternoon, matching their most in a first half since Week 3 of the 2013 season.

Tailback Damien Williams later extended the lead with a 4-yard scoring plunge midway through the second quarter, marking the veteran running back's sixth touchdown in his last four games.

It all helped the Chiefs build a sizable lead headed into halftime as Kansas City looks to lock up a third-straight division title and the top speed in the AFC.
