DENVER -- The Los Angeles Chargers found a new way to lose during their rough season Sunday, falling 23-20 after a last-second pass interference penalty.
The infraction was called on cornerback Casey Hayward, a 37-yard mark-off that set up Brandon McManus' game-winning 53-yard field goal as time expired.
Denver took over for the final possession at its own 28-yard with only nine seconds remaining.
The Chargers appeared to send the game into overtime on a 46-yard field goal by Michael Badgley with 14 seconds remaining.
The kick came after they converted a fourth-and-11 following consecutive false start penalties on offensive linemen Dan Feeney and Russell Okung.
Mike Williams made a mostly one-handed catch over Denver cornerback Isaac Yiadom for a 38-yard gain and first down at the Denver 38-yard line with two minutes remaining.
Playing a Denver team missing pass rushers Von Miller and Bradley Chubb and starting a rookie quarterback, the Chargers instead looked like the undermanned team for most of Sunday.
Oddly, they were actually as healthy as they've been all year.
All-Pro safety Derwin James made his season debut after missing the first 11 games because of a stress fracture in his right foot.
Safety Adrian Phillips, a 2018 All-Pro on special teams, also played for the first time since Week 2 when he broke his arm during a loss in Detroit.
