The Kansas City Chiefs lead the Oakland Raiders, 21-10, at halftime from Arrowhead Stadium.

Tyreek Hill was the story of the first half. He scored two touchdowns in the second quarter to help the Chiefs score 21-straight points including a 78-yard punt return for a touchdown.

Chiefs quarterback Alex Smith is 11 of 16 for 202 yards and a touchdown.

The Raiders offense went three-and-out on their first possession, but on their punt to the Chiefs, Hill fumbled the football. Oakland linebacker James Cowser jumped on it, giving the ball right back to the Raiders with good field position at the Chiefs 38-yard line.

They Raiders took the 3-0 lead with a 44-yard field goal by Sebastian Janikowski.

The Chiefs struck back at the beginning of the second quarter, when facing second-and-10 at the Oakland 36-yard line, Hill ran a beautiful post route, and Smith hit him in perfect stride for the touchdown and 7-3 lead.

After another Raiders three-and-out, the Chiefs started their next drive at the 22-yard line. Smith hit Kelce for a gain of 28 and Conley for a gain of 31 yards to get the Chiefs in Oakland territory. At the Oakland 20-yard line, Smith found Hill for a gain of 16 yards, and two plays later, RB Charcandrick West ran it in for the 3-yard touchdown and 14-3 lead.

The next Raiders drive stalled, and the Raiders punted it to Hill, who took it back 78 yards for a touchdown and 21-3 lead.

The Raiders' ensuing possession began at the 8-yard line with a little more than six minutes left in the second quarter. In 13 plays, Derek Carr worked the Oakland offense down the field, and a defensive pass interference penalty on Terrance Mitchell brought the Raiders to the Chiefs goal line. From there, RB Latavius Murray ran it in for the touchdown, cutting the lead to 21-10 Chiefs at the half.

WR Chris Conley has two receptions for 70 yards. Mitchell leads the Chiefs in tackles with four. Justin Houston and Rakeem Nunez-Roches split a sack.

LB Derrick Johnson left the game near the end of the second quarter due to an Achilles injury.

The Chiefs will receive the ball to begin the third quarter.
