Albert Breer of The MMQB reported the quarterback will be in attendance for the Patriots' mandatory minicamp, which begins this week.
Brady, 40, had missed all of the team's voluntary workout program. He and tight end Rob Gronkowski instead chose to work out and receive treatment at the TB12 clinic, which is run by Brady's trainer, Alex Guerrero.
Gronkowski said Sunday night he will be attending the mandatory program.
"We've got mandatory minicamp this week, so I'll be there this week," Gronkowski said at a charity event, per CBS Boston. "I'll be full go. I'm looking forward to it. Can't wait to get back to work. I'm excited."
Brady and Gronkowski are each seeking new contracts. The quarterback will make a $14 million base salary in 2018 and 2019, probably less than half what he'd make if he hit the open market. His base salary is fifth among quarterbacks, per Spotrac. His 2018 cash ranks in a tie for 18th.
Gronkowski is slated to make $8 million in 2018 but has no guaranteed money left on his contract. James Palmer of NFL Network reported last month the Patriots were working on a restructuring. That deal has not been completed.
It's no real surprise to see the Patriots' two franchise faces at mandatory workouts. The Patriots could begin fining them had they not shown up. Absences would have also only exacerbated public focus on the strained relationship between Gronkowski, Brady and coach Bill Belichick, who has bristled at his stars' reliance on the TB12 treatment.
