Jalen Richards is out for the rest of the season after suffering a torn pectoral tendon during the Raiders’ Week 1 loss to the Giants.
Richards, a fourth-round pick, missed the first six games of the regular season after tearing his pectorial tendon in a preseason game against the Eagles.
He was replaced by rookie Matt McGloin.
Richarts suffered the injury in the first quarter of the Raiders first win of the year, a 21-10 win over the Vikings on Sept. 3.
Richers was limited during the first three games of that series, as he had to sit out the final three games due to a strained left hamstring.
The Raiders went 2-2 in his absence.
Richys was able to return to practice on Tuesday but will not be available for Week 3.
He is the first Raiders player to miss the first month of a season with a torn tendon since defensive end Mario Edwards injured his hamstring on Dec. 20, 2015.
Richies had six tackles, including two sacks, and two quarterback hits during the regular-season finale against the Vikings.
He had a sack in the Raiders final win over New Orleans.
