The Kansas City Chiefs have scored 21 unanswered points and lead the New Orleans Saints, 21-7, through two quarters of play at Arrowhead Stadium in Kansas City, Missouri.

Chiefs running back Spencer Ware has 104 yards from scrimmage and a touchdown.

The Saints struck first on a drive largely featuring quarterback Drew Brees and the passing game. Brees completed five passes to three different receivers for a total of 61 yards on the drive, capping it off with a 9-yard touchdown to wide receiver Brandin Cooks and a 7-0 lead.

The Chiefs answered rather quickly. Facing third-and-7 on the Kansas City 28-yard line, QB Alex Smith hit WR Jeremy Maclin for an 8-yard gain. An 18-yard rush by WR Tyreek Hill brought the Chiefs into New Orleans territory, and a 46-yard touchdown pass from Smith to Ware tied the game at 7 with a little more than four minutes left in the first quarter.

The Saints faced third-and-12 at their own 39-yard line on their next possession and on a pass intended for WR Willie Snead, safety Eric Berry deflected the ball in the air and into the hands of Daniel Sorensen, who returned the ball 48-yards for a Kansas City touchdown and the first of his career.

The Chiefs added to their lead in the second quarter on a first-down play at the New Orleans 38-yard line. Hill ran deep down the left sideline, and Smith aired it out for him deep. Hill jumped up, beat Saints cornerback Ken Crawley and made a one-handed catch for the score to make it 21-7.

Smith is 10 of 15 for 142 yards passing and two touchdowns. Berry leads the team with five combined tackles (4 solo) and Sorensen has the game's only sack.

The Saints will receive the ball to begin the second half.
