DENVER — The Denver Broncos sent rookie Tua Tagovailoa tottering to the sideline, benched early in the fourth quarter after his worst game as a pro, one that included six sacks and just 83 yards passing.
For doing such a good job, they nearly paid a big price.
Justin Simmons intercepted Ryan Fitzpatrick's pass to DeVante Parker in the end zone with 63 seconds left Sunday, sealing the Broncos' gritty 20-13 win over the Miami Dolphins.
"I was happy as hell," said Melvin Gordon, who rushed for two touchdowns but fumbled on the way in for his third score, giving the Dolphins (6-4) one last chance.
The Broncos (4-6) snapped Miami's five-game winning streak and kept Tagovailoa from joining Ben Roethlisberger as the only rookie QBs in the past 40 years to win their first four starts.
But they had to sweat out Fitzpatrick's long drive at the end.
With Gordon about to score his third touchdown, linebacker Andrew Van Ginkel atoned for a pair of penalties on the previous play by punching the ball loose at the 1 and safety Eric Rowe recovered.
Fitzpatrick, who drove Miami to a field goal after replacing Tagovailoa, started at his 1 and drove the Dolphins to the Denver 15-yard line, where his third-and-8 pass was picked off by Simmons.
