Raiders QB Mariota placed on IR

The Las Vegas Raiders placed backup quarterback Marcus Mariota on injured reserve Saturday after he hurt his quadriceps on his only snap in the season opener.

Mariota came on for one play in the first quarter for the Raiders in Monday night’s 33-27 overtime win over the Baltimore Ravens. He ran for 31 yards but reinjured his quadriceps and didn’t return despite the Raiders having planned a package of plays for him.
