The Broncos' wide receiver was well on his way to an 85-yard touchdown when he tripped over the 45-yard-line and was quickly brought down by Chargers defenders. The Broncos were trailing 10-0 at the time.
To add insult to injury, three plays later Peyton Manning threw an 80-yard pick six to Quentin Jammer. It's just that kind of night for the Broncos.
