Minnesota Vikings running back Adrian Peterson said he “got a fair game” Friday in a hearing over his NFL-issued suspension.

Peterson was in U.S. District Court in Minneapolis as attorneys for the NFL Players Association and the NFL made their cases to U.S. District Judge David Doty, who deferred a ruling until after he considers the arguments.

The NFLPA is asking Doty to end a suspension the NFL administered in the wake of Peterson’s child-abuse case.

Peterson entered a no-contest plea to a misdemeanor charge of reckless assault in November, and NFL commissioner Roger Goodell suspended Peterson, declaring him ineligible to return to the league until April 15.

—Seattle Seahawks defenders Bruce Irvin and Michael Bennett and New England Patriots tight ends Rob Gronkowski and Michael Hoomanawanui were fined by the NFL for their roles in a brawl near the end of the Super Bowl last Sunday.

Irvin, who was ejected for being the “instigator,” reportedly received the highest fine: $10,000. The rest were docked $8,268. Those fines are in addition to an $11,025 penalty meted out earlier this week to Seahawks wide receiver Doug Baldwin for an obscene touchdown celebration in the third quarter.

Irvin, Bennett and Gronkowski were fined for “unnecessarily striking an opponent” and Hoomanawanui was penalized for ripping off an opponent’s helmet.

—The Oakland Raiders hired Ken Norton Jr. to coordinate their defense.

Norton joins the staff of new coach Jack Del Rio, who played linebacker with Norton with the Dallas Cowboys from 1989 to 1991.

The Raiders also reportedly hired University of Miami defensive line coach Jethro Franklin for the same job.

Norton had spent the past five seasons coaching linebackers with the Seattle Seahawks, who have been the No. 1 scoring defense for three years running and the No. 1 total defense for the past two.

— The Seahawks reportedly promoted Kris Richard to be their defensive coordinator.

Richard has been Seattle’s secondary coach since 2010, when he came to the Seahawks from USC along with coach Pete Carroll. He had been considered the favorite to replace Dan Quinn, who left after two years in charge of the NFL’s No. 1 defense to coach the Atlanta Falcons.

According to Alex Rozier of King 5-TV, Carroll told the team about Richard’s promotion Friday after Norton was named the Raiders’ coordinator.

Rocky Seto, another defensive assistant, also received a promotion, according to Rozier.

—Pittsburgh Steelers running back Le’Veon Bell will spend 15 months on probation stemming from his arrest on marijuana possession and DUI charges.

Bell, 22, entered into a court-mandated program Friday that, if completed, will result in the charges being dropped from his record.

Bell was arrested on Aug. 20, 2014, in Ross Township, a suburb just north of Pittsburgh, after being pulled over by a police officer. The officer said he smelled marijuana coming from the car, and Bell was charged with driving under the influence and possession of the drug. Police found 20 grams of marijuana in the vehicle.

Also arrested in that traffic stop was LeGarrette Blount, Bell’s then-teammate who is now with the New England Patriots. Blount completed 50 hours of community service in Boston and had his marijuana charge dropped last week.

—The Steelers promoted Jerry Olsavsky to inside linebackers coach and Joey Porter to coach the outside linebackers.

From 2010 to 2014, Olsavsky served as a defensive assistant with the Steelers, whose defense ranked in the top two three times and was the top overall defense twice.

In 2014, Porter also served as a defensive assistant. He played eight years for the Steelers (1999-2006).

—Authorities in Wichita, Kan., have dropped a drug charge against Dallas Cowboys running back Joseph Randle, and the mother of Randle’s son has filed a petition for protection from abuse.

Randle, 23, was cited for marijuana possession earlier this week after police were called to a Wichita hotel to investigate a domestic disturbance. Police dropped the drug charge Friday, leaving open the possibility of refiling it once they conclude their investigation.

The petition, filed by Dalia Jacobs in Sedgwick County Court in Wichita, Kan., alleges that Randle pointed a gun at her car, threatened to “blast the vehicle” and punched out one of the vehicle’s windows.

—The Indianapolis Colts hired longtime NFL assistant Jim Hostler as wide receivers coach and announced four other coaching changes.

The team also named Tim Berbenich as defensive assistant, Hal Hunter as offensive line coach, Brad White as outside linebackers coach and moved former wide receivers coach Charlie Williams to running backs coach.

Hostler holds 25 years of coaching experience, including 15 seasons in the NFL. In 2014, he served as the senior offensive assistant for the Buffalo Bills.

—Miami Dolphins coach Joe Philbin officially named Terrell Williams as defensive line coach.

Williams, 40, comes to the Dolphins with 17 years of coaching experience, including three seasons as the defensive line coach for the Oakland Raiders and 14 years in the college ranks. He joins the Dolphins from Florida, having been named the school’s defensive line coach on Jan. 3.

—Houston Texans coach Bill O’Brien plans to open up the competition at quarterback after playing four players in 2014.

The Texans finished with a 9-7 record last season despite struggling at the quarterback position because of injuries.

“We’ll make the right decision and it will probably be a competition,” O’Brien said on Texans radio. “It will be something where guys come in and compete and have to win the job and that’s the way it should be and that’s what we’re looking to do.”

—The New England Patriots signed 12 players to future contracts.

In addition to signing the nine practice squad players, the Patriots signed defensive lineman Antonio Johnson, linebacker Rufus Johnson and running back Dion Lewis.

Offensive lineman Chris Barker, defensive end Jake Bequette, quarterback Garrett Gilbert, defensive back Justin Green, offensive lineman Caylin Hauptmann, wide receiver Jonathan Krause, linebacker Eric Martin, linebacker Deontae Skinner and defensive back Daxton Swanson all finished the season on New England’s practice squad.
