Raiders quarterback Derek Carr went into the locker room at Allegiant Stadium on Thursday night with a strained left groin injury and later was ruled out.
He went out of bounds on a third-and-goal play late in the first quarter against the Los Angeles Chargers and immediately began hobbling.
Marcus Mariota, the former Tennessee Titans starter who was signed in the offseason, replaced Carr. He quickly took the Raiders on an 86-yard drive, hitting tight end Darren Waller on a 35-yard touchdown.
