Jackson is fined for role in brawl

Jackson was not suspended for making contact with an official during Sunday’s brawl between the Raiders and Broncos — but he will pay a fine.

The NFL on Friday announced a $30,387 penalty for Jackson, the standard amount listed on the league website for a first offense of physical contact with a referee.

Jackson was one of three players ejected — along with Raiders receiver Michael Crabtree and Broncos cornerback Aqib

Talib — for their actions in the melee.

Jackson was one of the first Raiders players to run toward the sideline as Crabtree was being swarmed by Broncos players. As Jackson got there, he ran into the back of official Laird Hayes, who fell forward and appeared to grab his chest.

In a letter to Crabtree, the NFL wrote that one of its officials was “injured trying to maintain control of the situation.” According to Albert Breer of The MMQB, the NFL Referees Association sent a letter to commissioner

Roger Goodell saying Hayes had visited a doctor for bruised ribs and shortness of breath.

The NFLRA wrote Goodell that it was “very concerned” Jackson was not suspended after the incident, The MMQB reported. Raiders head coach Jack Del Rio, however, said he thought the contact was incidental.

“I don’t think ( Jackson) would intentionally do anything like that,” Del Rio said Monday.

Crabtree and Talib were each suspended one game by the NFL. Denver linebacker Shane Ray was also reportedly fined $12,154 for unsportsmanlike conduct.

Amari Cooper (concussion/ankle), who did not practice during the week, was ruled out for Sunday’s game against the Giants.

Cooper suffered both injuries on a hit from Broncos safety Darian

Stewart. Stewart was fined $24,308 by the NFL for the play, but reportedly planned to appeal the fine.

Del Rio initially described the hit as “vicious” before softening his stance on it Monday. Cooper had extended for a pass on an inside route and appeared to lower his head just before colliding with Stewart, who lowered his shoulder into the back of Cooper’s head and neck.

With Crabtree suspended, Seth Roberts and Cordarrelle Patterson are in line to be the primary receivers Sunday, although Patterson is questionable with a hip injury.

Familiar face: Raiders right tackle Marshall

Newhouse spent the previous two seasons protecting quarterback

Eli Manning while starting 20 regular-season games and one NFC Wild Card game for the Giants. Manning’s streak of 210 consecutive regularseason starts will end Sunday, as the Giants intend to start Geno Smith.

“I have a reaction,” Newhouse said of the quarterback change. “But I’ll keep it private.”

Newhouse is more concerned this week with a Giants defense he went against often in practice and described Friday as “still stout.” The Giants rank 31st in the league in total defense but have a formidable pass rusher in

Jason Pierre-Paul, who has a team-high 6.5 sacks.

“When I (played) there we went against each other often, so there’s definitely a familiarity,” Newhouse said. “But he’s grown as a rusher. Obviously they paid him and he’s produced and he’s gotten better. It’ll be a test for sure.”

Newhouse said it has been “surprising” to see the Giants — who won 11 games last season — struggle in 2017. Poor play and injuries — the Giants have 18 players on injured reserve — have contributed to a 2-9 record.

“I know there’s a lot of prideful, high-character people involved in all that, and so it just doesn’t seem like that’s something that could or should happen,” Newhouse said. “But that just goes to show you how fickle this business is.” Injury report: Cornerback David Amerson was a limited participant in practice this week and is listed as questionable for Sunday’s game. Amerson has missed the past four games with a foot injury but said he hopes to play this weekend.

“That’s still a question mark for us,” Del Rio said Friday. “But it was good to have him back out moving around.”

Cooper is the only Raiders player ruled out for Sunday. In addition to Patterson, Jackson (ankle) and linebacker Cory

James (knee) are questionable. Matt Kawahara is a San Francisco Chronicle staff writer. Email: mkawahara @sfchronicle.com Twitter: @matthewkawahara
