Watch: 49ers' Raheem Mostert scores 80-yard TD on first play of game

The New York Jets wanted to bounce back against the San Francisco 49ers in Week 2 after a season-opening loss to the Buffalo Bills last week. It already isn't going well for New York, though, as they allowed a score on the first play of Sunday's game. 

49ers running back Raheem Mostert carried the ball 80 yards for a touchdown. According to USA Today's Doug Farrar, Mostert went 23.1 miles per hour on the run, which is the fastest anyone's been tracked in the NFL over the last two years. 

This is the second week in a row that the Jets have fallen behind in the first half. They went down 21-0 to the Bills in Week 1 before losing 27-17.

San Francisco also is looking for its first win of the season after a season-opening loss to the Arizona Cardinals. Thanks to Mostert, the team is off to a good start.
