The New England Patriots and quarterback Tom Brady are expected to add performance-based incentives to his current contract, ESPN.com's Adam Schefter reports.
According to the report, the contract is set to be finalized in the next 24 hours and will his compensation in line with the league's highest paid signal callers.
The incentives could total $5 million. He is set to make $15 million in base salary for the 2018 season.
In March 2016, Brady signed a two-year, $41 million extension with more than $28 million in guarantees.
The top five quarterbacks that have the highest guarantees in salary are all signed through at least the 2022 season. Atlanta Falcons quarterback Matt Ryan is the top-earning in the NFL at the quarterback position after he signed a five-year, $150 million contract in May.
The recently-turned 41-year-old Brady has two years remaining on his contract. He has eyed a new deal before the start of the regular season, and the Patriots have shown willingness in past years to accommodate their franchise signal-caller.
Brady finished the 2017 season with 4,577 yards passing and 32 touchdowns against eight interceptions en route to being named the NFL's Most Valuable Player, marking the third such recognition on his decorated career.
The future Hall of Famer, uncharacteristically skipped voluntary workouts in May. He was asked if his absence was related to his contract.
"I've never talked about my contract," Brady said at the time. I've never brought up money for a lot of reasons that I've said over the years. Those things are very personal."
Meanwhile, team owner Robert Kraft said in April that Brady's contract wasn't a concern.
"He'll be 41 when the season starts," Kraft told The Athletic's Jeff Howe. "Neither side has an issue with it. If it becomes an issue, we'll deal with it."
"He is a great person, man. He has been like a second father to me in so many ways," Brady said of Kraft at the time. "I have a great relationship with Coach Belichick. We've worked together for 18 years. There's no coach I'd rather play for, and I've loved my experience here. I certainly couldn't be the player I am today without playing for such a great coach. So I see these as all positive things."
