The Kansas City Chiefs lead the San Diego Chargers, 20-10, at halftime at Qualcomm Stadium in San Diego, Calif. Alex Smith is 11 for 15 for 176 yards, one touchdown passing and one touchdown rushing.

The Chargers and Chiefs traded 35-yard field goals to begin the game, and then San Diego took back over.

Starting at their 24-yard line, the Chargers used a good mix of run and pass to get into Chiefs territory. When a third-and-3 pass to tight end Antonio Gates left the Chargers a yard short, they opted to go for it. Running Back Andre Williams ran up the middle 5 yards for the first down.

The first quarter concluded with the Chargers at the Chiefs 5-yard line.

After a defensive holding penalty called on safety Ron Parker, Philip Rivers hit Gates for a 2-yard touchdown and 10-3 lead.

 The Chiefs were able to get the offense going on the ensuing drive.

With the Chiefs starting at their own 25-yard line, Smith passed to Jeremy Maclin for 10 yards, then Charcandrick West for 18. Smith then hit Albert Wilson to his left on a screen, and Wilson took it 42 yards before being pushed out of bounds at the San Diego 5. On first-and-goal, Smith rushed 5 yards for a touchdown rushing to tie the game at 10.

The Chargers pushed it to their own 40 on their next drive, but facing third-and-8, Rivers threw to his right into the hands of cornerback Marcus Peters for his sixth interception of the season. Peters returned the interception 16 yards to the San Diego 34.

The Chiefs took advantage of the short field position by driving to the Chargers 4-yard line in nine plays. On first-and-goal, Smith ran a play-action play and found West open in the end zone for the 4-yard touchdown and 17-10 Chiefs lead.

The Chargers faced second-and-7 at the Kansas City 18-yard line, and Rivers threw a deep pass into the right part of end zone intended for wide receiver Isaiah Burse. Back in coverage, Safety Daniel Sorensen picked the ball off and managed to get two feet in bounds before he fell out for the touchback.

Chiefs kicker Cairo Santos hit a 25-yard field goal as the second quarter concluded for a 20-10 halftime lead.

Linebacker Ramik Wilson leads the Chiefs in tackles with seven (six solo).

The Chiefs receive the ball to begin the third quarter.
