SAN DIEGO (AP) – Justin Houston intercepted Philip Rivers’ pass and returned it 17 yards for a touchdown and 346-pound defensive tackle Dontari Poe leaped over the pile for a 1-yard touchdown and the Kansas City Chiefs embarrassed the free-falling San Diego Chargers 33-3 Sunday.
Alex Smith won again at Qualcomm Stadium as the Chiefs (5-5) won their fourth straight game following a five-game losing streak.
The Chargers (2-8) lost their sixth straight.
Rivers had his worst game of the season, throwing for just 178 yards. Rivers attempted a pass to Danny Woodhead from the Chargers 23 and Houston intercepted it and ran it in for a 19-3 lead with 3:27 left in the third quarter.
Houston sacked Rivers four times in the 2014 season finale in which the Chargers were eliminated from the playoff race.
Smith, who led Helix High to consecutive city championships at Qualcomm Stadium, was 20 of 25 for 253 yards.
