What happened: Las Vegas Raiders cornerback Darien Porter was ruled out with a groin injury during Sunday's game against the New York Jets. Porter was previously listed as questionable to return before being downgraded. He will not return to the contest.

Why it matters: Porter's departure strains the Las Vegas secondary against New York's passing attack. The second-year defensive back out of Iowa State has functioned as an important rotational piece in coverage and on special teams units.

What to watch: Las Vegas will evaluate the severity of Porter's injury following the game. The team will provide an update when practice resumes ahead of next week's schedule.
