WATCH: Brandon McManus gives Broncos thrilling victory over Chargers

A thrilling finish gave the Broncos a victory over the Chargers in Drew Lock’s first start at QB.

The Los Angeles Chargers kicked a field goal with eight seconds left in Denver Sunday to tie the game with the Broncos at 20-20. With a rookie making his first start at QB in Drew Lock, for sure Vic Fangio would have the former Missouri star take a knee and head to overtime.

Not so fast. After Lock kept looking at the playsheet/wristband, he took the snap and unloaded. Chargers DB Casey Hayward clobbered Courtland Sutton and pass interference was called.

Lock was overjoyed at the penalty.

The 37-yard penalty gave Brandon McManus a shot at a long field goal.

And he was true. McManus, who wanted to try a 65-yarder at the end of the first half but was denied by Vic Fangio, nailed the kick for a 23-20 victory.

And Lock celebrated as one would after their first victory as a starting quarterback.
