"We have a contract now until he's 40, but he'd like to play beyond that," Kraft said at an NFL press conference on concussion prevention, via USA Today. "We want to make sure that he's healthy and can do everything. He takes a lot of hits, and we have to be sure he's being treated (well), his medical health is paramount, and he can function for many years to come."
Brady, who turns 36 in August, just signed a team-friendly, $27 million extension that takes his contract through the 2017 season.
Kraft insisted recently the contract isn't a fake deal designed to be redone, even though it pays the three-time Super Bowl champ below-market salaries of $7 million, $8 million and $9 million from 2015-17.
Brady threw for 4,827 yards and 34 touchdowns against eight interceptions last season but faltered in the AFC Championship Game, throwing two picks and posting a 62.3 passer rating in the 28-13 loss to the Ravens.
