KANSAS CITY, Mo. (AP) – The Kansas City Chiefs kept the San Diego Chargers out of the end zone twice in the final seconds Sunday, preserving a 10-3 victory and their seventh consecutive win.

Alex Smith threw for 191 yards and a touchdown, along with his first interception after a franchise-record 312 attempts. But it was a banged-up defense that held San Diego without a touchdown for the second time this season that allowed the Chiefs (8-5) to escape.

The Chargers (3-10) took over at their own 11 with 5 minutes left and quickly moved into Kansas City territory, converting fourth down three times. But after San Diego was called for delay of game at the Chiefs 1 with 5 seconds left, Philip Rivers threw incomplete into the end zone.
