Eli Manning signed a four-year, $84 million contract extension with the New York Giants on Friday.

The Giants announced the deal with the two-time Super Bowl MVP two days before the season opener at Dallas.

The new deal will make Manning, 34, the NFL's fourth-highest-paid quarterback, with an average salary of $21 million. Green Bay's Aaron Rodgers is the highest paid with a $22 million annual salary, followed by Seattle's Russell Wilson and Pittsburgh's Ben Roethlisberger.

Patriots cleared in headset case

•The NFL said the New England Patriots had nothing to do with audio interference that rendered the Pittsburgh Steelers coaching headsets useless during the first quarter Thursday night. An NFL statement said the problem was "entirely attributable to an electrical issue made worse by the inclement weather." Frustrated, Patriots coach Bill Belichick said "it's just not right" that his team is repeatedly being accused of cheating.

•Receiver A.J. Green agreed to a contract extension on Friday that runs through the 2019 season and said his deal was comparable to the five-year, $71 million contract that Atlanta gave Julio Jones in late August. Green said his deal was modeled after Jones'.

Robert Griffin III was cleared to compete following the third concussion of his career, but coach Jay Gruden wouldn't say whether he will play Sunday against Miami.

•The Oakland Raiders signed troubled pass rusher Aldon Smith, five weeks after he was released by San Francisco because of his fifth legal run-in.


Former Iowa star Roy Marble dies

Roy Marble, the guard who scored the most points in Iowa history as he helped the Hawkeyes become a national power in the mid-1980s, died Friday in Grand Blanc, Mich., after a long battle with cancer, according to school officials. He was 48.

Marble was a prep star from Flint before leaving his home state to play for the Hawkeyes from 1986-89, scoring 2,116 points and headlining perhaps the best years the program has ever seen.

Marble led Iowa to the NCAA tournament four times and to the Elite Eight in 1987, when the Hawkeyes reached No. 1 in the polls.

Marble's son, Roy Devyn Marble, earned first-team All-Big Ten honors at Iowa in 2014. He played for the Orlando Magic last season.
