The Giants won't have a lame-duck quarterback in 2015. They'll have a wealthy one.

Eli Manning, who was heading into the final year of his contract, reportedly will sign a four-year extension with the team Friday. According to the NFL Network, the $84-million extension was being finalized Thursday night and was expected to be inked in the morning.

"Just a few details are left," the report said.

It's unclear whether the contract will affect any of the $17 million in base salary Manning was due to earn this season, or if it will convert any of it into bonuses that can alleviate the salary-cap impact of his very high numbers.

The average over the four years of the reported deal would be $21 million, or $1 million per year less than what Aaron Rodgers makes as the highest-paid quarterback in the league.

The deal will be in line with recent extensions signed by Ben Roethlisberger ($21.85 million per season) and Philip Rivers ($20.85 million). Manning's deal reportedly will include $65 million in guaranteed money, which is what Rivers received. Roethlisberger had $31 million guaranteed.

More importantly to the Giants, it gives them five more seasons with Manning, who will be 39 when this deal expires, virtually guaranteeing that he will play his entire career with the team.

Manning may have spurred the deal to completion with his comments in a radio interview on Tuesday. He said he hoped the extension would be completed before the regular season and said he preferred not to negotiate past Sunday's opener against the Cowboys.

He later insisted that he was not setting a deadline, but whatever he'd like to call it, it worked.

Manning has been uncomfortable about discussing the contract extension throughout the summer as the two sides worked toward the agreement. He angrily denied his desire to be the highest-paid quarterback in the NFL, even though some early proposals from his side would have made him just that. And he shrugged off comparisons with other deals as quarterbacks such as Rivers and Russell Wilson signed their extensions.

On Wednesday, Manning was asked if there was anything in the world he would less like to be discussing with reporters than the topic at hand.

"No," he said.

And now, for five more years, he won't have to.
