The Kansas City Chiefs hold a narrow lead over the San Diego Chargers at the break in their NFL clash at Arrowhead Stadium.

Both teams struggled to move the ball early on forcing two early punts but the Chargers opened the scoring on their second drive as Philip Rivers connected on a couple of throws to receiver Keenan Allen.

Although they could not score the touchdown, Nick Novak fired a 30-yard field goal through the posts.

This brought the Chiefs into life and Smith engineered a drive of his own which culminated in Andy Reid's side taking the lead as the quarterback drilled a pass to receiver Donnie Avery on a deep post for a 32-yard touchdown over the middle of the field.

The hosts extended their advantage as Smith put together another long drive to move them into the red zone. This time he handed the ball off to running back Jamaal Charles, who found space to go in for the seven-yard touchdown.

However, just before the break the Chargers reduced the deficit to four points as Rivers extended a play and threw the ball deep into the end zone where he connected with Danny Woodhead, who made an excellent grab for an 11-yard score.
