OAKLAND -- Raiders cornerback David Amerson had yet another strong game against Green Bay, proving he belongs in the team’s lineup next season. The Week 3 waiver claim had six tackles, three passes defensed and an interception in a 30-20 loss to the Packers.

He leads the NFL is passes defensed and has 23 as a Raider, which stands as a franchise record since the stat became official in 1994.

He broke up a deep pass intended for James Jones that prevented a huge gain. He had an interception in the fourth quarter that prevented another score.

“They ran the same play that I broke up earlier in the end zone,” Amerson said. “It was kind of the same thing, just more room for him to run. I knew it was coming and I was kind of behind him, trying to bait Aaron to throw it, which he did.”

That interception could’ve gone to Charles Woodson, but Amerson came down with it.

“I told ‘Wood’ it was tunnel vision,” Amerson said. “I just saw the ball and the next thing I know, I feel someone tugging at it. Then I saw it was him, but he was nice enough to let it go.”

Losing Super Mario ‘a blow’: Rookie defensive lineman Mario Edwards injured his neck in the first half of Sunday’s loss and never returned. Del Rio said further evaluation is required to know the extent of his injury, though recovering on a short week might prove difficult.

Rushing the passer become harder without Edwards in the mix, especially on the interior during passing situations.

“We had some early pressure, got him sacked a couple of times. Mario, obviously, has become a real key member of our defensive front and having him go out early like he did definitely was a blow.”

The Raiders also lost slot receiver Seth Roberts to an abdominal injury. He did not return.

Run game flames out: Raiders running back Latavius Murray got off to a fast start, with 15 carries for 64 yards in the first half. He only had 14 yards on six carries in the second half, a slowdown in production and frequency at times where the Raiders needed steady yards and drives alike.

“I thought we were able to do some things early,” Del Rio said. “Like you said, we didn’t do so well late. I will say, any time the run game doesn’t get the number of turns that you want to have, typically that is the result of not converting first downs. Moving the chains and converting first downs gives you more opportunity to do a lot things; you can be productive on offense.”

Mack gets another sack: Second-year pro Khalil Mack had an early sack, but none after that, a week after he recorded five against the Denver Broncos. He was still impactful, with a sack, a quarterback hit and another tackle for loss.

Mack has 15, one behind Derrick Burgess’s all-time record.
