Ed Sabol, a Pro Football Hall of Fame member who revolutionized the presentation of the NFL through his NFL Films productions, died Monday at age 98.

Sabol, who was inducted into the Hall of Fame in 2011, started NFL Films in 1962 and turned it into a major portal for relaying the sights and sounds of the NFL to fans. Among his innovations, Sabol presented highlights to musical accompaniment and initiated the use of microphones on players and coaches to capture the sounds of the game.

NFL Films won 52 Emmy Awards during Sabol’s run through 1995. Ed’s son, Steve, took over NFL Films in 1985. He died in 2012 at age 69.

— Carolina Panthers defensive end Greg Hardy’s domestic-abuse case was abruptly dismissed Monday because his accuser could not be found to testify.

The prosecution said repeated attempts to reach Nicole Holder, Hardy’s ex-girlfriend, failed and the domestic violence charges were dismissed.

“Due to the circumstances of this case, the victim’s testimony would have been critical evidence for the jury to consider,” District Attorney Andrew Murray said in a statement. “The victim appears to have made herself unavailable to the state.”

The district attorney’s office said it has “reliable information” that Holder and Hardy have reached a civil settlement.

Hardy was convicted last summer of assaulting and threatening to kill his former girlfriend. He appealed the ruling and was assigned for a jury trial that was to start Monday morning at the Mecklenburg County Courthouse in Charlotte.

— The Seattle Seahawks promoted defensive backs coach Kris Richard to defensive coordinator and announced the hiring of three other assistant coaches.

Brennan Carroll, son of Seattle coach Pete Carroll, will join his father and his brother, Nate, in Seattle as assistant offensive line coach. Brennan previously coached tight ends and receivers at the University of Miami.

The Seahawks hired Miami’s linebackers coach, Michael Barrow, to fill the same role in Seattle. Former Seahawks linebacker Lofa Tatupu will assist Barrow, who played linebacker for 13 years in the NFL. They replace Ken Norton Jr., who left last week to become the defensive coordinator of the Oakland Raiders.

— The San Francisco 49ers announced new coach Jim Tomsula’s coaching staff, a 19-man group that includes seven holdovers from former coach Jim Harbaugh’s staff.

The returning coaches: offensive coordinator Geep Chryst (promoted from quarterbacks coach), defensive coordinator Eric Mangini (promoted from tight ends coach), Tom Rathman (running backs), D.J. Boldin (offensive assistant), Ejiro Evero (defensive assistant), Mick Lombardi (defensive assistant) and Ronald Curry (wide receivers).

As previously reported, Tomsula has four former defensive coordinators, including secondary coach Tim Lewis and linebackers coaches Clancy Pendergast and Jason Tarver. Tomsula’s other defensive assistants are line coach Scott Brown and former defensive lineman Aubrayo Franklin.

On offense, Chris Foerster and Eric Wolford will coach the line, Adam Henry the wide receivers, Steve Logan quarterbacks and Tony Sparano tight ends.

Thomas McGaughey Jr. and Richard Hightower will coach special teams.

—The Buffalo Bills officially signed offensive guard Richie Incognito.

Terms of the contract were not announced, but ESPN reported it is a one-year deal worth $2.25 million.

Incognito, 31, was out of the NFL last year after he served an eight-game suspension in 2013 for bullying former Miami Dolphins teammate Jonathan Martin.

Incognito was cleared last summer to play again after a league investigation found Incognito and fellow offensive linemen John Jerry and Mike Pouncey harassed Martin, who was later traded to the San Francisco 49ers.

—Brett Favre announced on his website Monday that he will return to Lambeau Field in 2015 to be inducted into the Green Bay Packers Hall of Fame and have his No. 4 jersey retired by the team.

The Packers previously announced that Favre will be inducted into the Packers Hall of Fame on Saturday, July 18, during the annual banquet at Lambeau Field. Also that night, the uniform No. 4 that he wore for the Packers from 1992 to 2007 will be retired.

Favre and the franchise have been in the process of healing an acrimonious divorce that occurred when the team moved forward with Aaron Rodgers as the quarterback. But tension between Favre and the Packers have cooled since his retirement from the NFL after the 2010 season.

—Green Bay coach Mike McCarthy is strongly considering handing off his play-calling duties to offensive coordinator Tom Clements.

The Green Bay Press-Gazette confirmed a WDUZ radio report that Clements likely will be given the title of associate head coach and wide receivers coach Edgar Bennett could be promoted to offensive coordinator.

The changes would be the next round of offseason staff adjustments since Green Bay’s 28-22 meltdown overtime loss to the Seattle Seahawks in the NFC Championship Game. McCarthy fired special teams coach Shawn Slocum on Jan. 30, and assistant special teams coach Ron Zook is expected to replace him.

—Trent Richardson’s two-game suspension by the Indianapolis Colts was the culmination of a season in which the running back gained weight and failed to communicate with the team, according to a report.

Already in the doghouse for gaining 15 pounds during the season, Richardson was suspended before the AFC Championship Game because he missed the walkthrough without alerting the team, ESPN.com reported. Richardson later said it was a family emergency and his cell phone was not working.

Listed at 5 feet 9 and 225 pounds, Richardson gained 15 pounds after a hamstring injury at midseason last year, ESPN.com reported.

He still has one game left on the two-game suspension — if he is still on the team next season. The team could decide to let him go and void $3.1 million in guarantees, according to ESPN.com.

—The Baltimore Ravens said they understood the decision of Jamal Lewis to sell an honorary Super Bowl ring they gave the former running back.

Lewis, one of seven players in NFL history to rush for 2,000 yards, sold the Super Bowl ring at auction for $50,820 on Sunday.

Lewis, who won a Super Bowl with the Ravens during the 2000 season, had been one of several Ravens legends to receive rings after Baltimore beat the San Francisco 49ers in Super Bowl XLVII.

Lewis, who signed contracts worth more than $30 million during his nine-year NFL career with Baltimore and the Cleveland Browns, declared for bankruptcy in 2012. He listed $14.5 million in assets and $10.6 million in debts, according to the Baltimore Sun.

—St. Louis Rams quarterback Sam Bradford is due nearly $13 million in 2015, but the team would like the oft-injured quarterback to restructure his deal.

Bradford, the No. 1 overall pick in 2010, has missed 25 of the past 32 games because of torn knee ligaments. In five seasons, he has missed 31 games.

This is the final season of Bradford’s rookie contract that was worth a maximum of $86 million.

With a $132.985 million salary in 2015, the Rams are likely to recommend a deal packed with performance-based incentives.

—The San Diego Chargers hired former John Carroll University defensive coordinator Chris Shula as a defensive quality control coach.

Shula is the grandson of former Miami Dolphins coach Don Shula, the winningest coach in NFL history.

In his only season at John Carroll, Shula helped the Blue Streaks to a record of 11-2 in 2014. The team ranked seventh in the nation in Division III in total defense and 10th in scoring defense.

—The Seattle Seahawks signed seven players, including two who spent time in training camp last season.

Guard C.J. Davis was placed on injured reserve in August, and wide receiver Kevin Smith, from the University of Washington, was released in final cuts.

The team also signed quarterback R.J. Archer, long snapper Luke Ingram, linebacker Brendan Kelly, defensive end Will Pericak and center Jared Wheeler.
