LOS ANGELES The Denver Broncos jumped out to an early lead but sputtered in the second half Thursday night, as the Los Angeles Chargers came from behind to earn a win in a game with playoff implications.For Denver, the wait continues at least another week to clinch its first playoff berth since 2015 as LA leapfrogs back into the AFCs No. 6 seed. Watch Denver7's postgame coverage in the video player belowThe Broncos amassed over 200 yards and 15 first downs en route to three long touchdown drives on their first three possessions and a 21-10 lead in the first half. They managed just three points over their final seven drives, though, and a defense that had come up with big play after big play in recent weeks failed to do so as the Chargers scored 21 unanswered points to take a late two-score lead.Penalties hurt the Broncos in an otherwise clean game. They were flagged seven times for 61 yards in a game in which they didn't turn the ball over.Broncos quarterback Bo Nix, who was thrice intercepted a week ago, completed 29 of 40 passes for 263 yards and a pair of touchdowns. Audric Estime was Denver's leading rusher with 48 yards and a score.Chargers quarterback Justin Herbert was 23-of-31 for 284 yards, two touchdowns and one interception.Thursdays game also featured a bit of obscure history. The Chargers converted the first fair-catch kick since 1976 on the last play of the first half. The NFL rulebook allows a team to attempt a kick from the spot of a fair catch rather than begin its next drive. Thanks to a 15-yard fair catch interference penalty on the Broncos, the Chargers had the ball at the Denver 47 and Cameron Dicker converted the 57-yard kick.The loss snapped a four-game win streak for Denver. The Broncos will once again try to secure a playoff spot in nine days, on the road against the Cincinnati Bengals, in another game airing on Denver7.
