SAN DIEGO -- A few thoughts on the San Diego Chargers' 23-20 loss to the Kansas City Chiefs at Qualcomm Stadium.

What it means: San Diego’s five-game winning streak ended with Kansas City’s first victory at Qualcomm Stadium since 2007. The Chargers fell to 5-2 on the year, 1-1 in the AFC West. It’s the fifth time in seven meetings between these two teams that a game has been decided by a field goal. Kansas City kicker Cairo Santos made the game winner, a 48-yard field goal, with 21 seconds left. The Chiefs improved to 3-3.

Chiefs play keep away: The Chargers were No. 3 in the NFL in time of possession heading into Sunday’s game. However, with a steady diet of running back Jamaal Charles (95 yards on 22 carries), the Chiefs dominated time of possession, keeping the ball away from San Diego’s explosive offense. Kansas City finished with a 39:00-21:00 edge in time of possession.

Gates closing in on history: Heading into Sunday’s contest against Kansas City, Chargers tight end Antonio Gates needed 90 receiving yards to pass Lance Alworth’s franchise record of 9,584 receiving yards. Gates finished with six catches for 61 yards and now has 9,556 career receiving yards.

Stock watch: Nick Novak hit field goals from 48 and 24 yards in the fourth quarter, breaking the franchise record for consecutive field goals with 31. The previous record of 29 had been held by John Carney, set over the 1992-93 seasons.

Oliver slowed down: After two straight games with over 100 rushing yards, undrafted rookie free agent Branden Oliver finished with just 67 rushing yards on 15 carries.

Game ball: Run-blocking tight end John Phillips got his first career touchdown as a Charger in the opening quarter, a 1-yard catch on a play-action pass from Philip Rivers. Phillips rebounded from a season-ending knee injury that cut short his 2013 season and has been a key part in San Diego’s resurgent running game.

What’s next: The Chargers have a quick turnaround, traveling to Denver to face the Broncos at 8:25 p.m. ET Thursday.
