The New York Giants and quarterback Eli Manning are reportedly close to coming to terms on a four-year contract extension worth $84 million. Ian Rapoport of NFL.com was the first with the news.

The two sides are said to be "finalizing" the deal, which could be signed as soon as Friday, per Rapoport. ESPN's Adam Schefter reports that the only thing keeping the deal from being signed is specific contract language, which may take the weekend to resolve.

It had been reported earlier this week that the Giants and Manning were making progress toward a deal that would see him remain with Big Blue, likely for the remainder of his NFL career, but there was no word at the time on value or term.

Manning has said repeatedly that he hoped a deal would get done soon, but seemed to indicate that he doesn't want to discuss a contract once the season begins and would play out the remainder of his current deal if the two sides were unable to come to terms prior to the Giants season opener against the Dallas Cowboys on Sunday night.

Manning, 34, has been the Giants starting signal-caller since the team traded for him in the 2004 NFL Draft. He's thrown for 39,755 yards and 259 touchdowns during his career and has led the Giants to two Super Bowl championships.

Under offensive coordinator Ben McAdoo last year, Manning enjoyed one of his best statistical seasons. With Odell Beckham Jr. set to embark on NFL Year Two and Victor Cruz likely to return from a patella injury soon, Manning could be set for even bigger things in 2015 and, from the sounds of it, beyond.
