News of Brady's impending surgery was first reported by The Boston Globe on Wednesday night.
According to The Globe, the surgery on Brady's right foot will address a lingering issue and will be performed at Massachusetts General Hospital by team physician George Theodore. The report says that Brady may have a screw inserted. If all goes well, he "should be ready for training camp," The Globe says.
Brady played much of this season with a stress fracture in his foot, but it did not affect his performance in the Patriots' loss to the New York Jets on Sunday, according to multiple media reports.
Brady was a full participant in three practices leading up to the Jets game.
On Nov. 10, Brady missed his first practice of the season. He was listed that day with a foot injury for the first time on the team's injury report. From that point on, it was common for Brady to be held out of Wednesday practices, while he was limited in practices the remainder of the week.
Brady was listed on the Patriots' injury report with a foot injury for the last eight regular-season games and its playoff game but played in all of them.
A league source told The Globe earlier Wednesday that the injury wouldn't keep Brady from playing in the Pro Bowl Jan. 30 in Hawaii, but the NFL on Thursday officially acknowledged that Brady has pulled out of the game and will be replaced by Kansas City Chiefs quarterback Matt Cassel.
In his weekly radio appearance Monday on Boston sports radio WEEI, Brady hinted that he wouldn't be playing in this year's Pro Bowl.
"We have exit physicals today," he said.
Brady added that his shoulder was bruised during Sunday's loss ("They got me pretty good," he said), but said that he wasn't figuring on needing any surgeries this offseason.
Brady had season-ending surgery after he injured his left knee in the opening game of the 2008 season. He played in every game in the 2009 season despite having hand and rib injuries for much of the second half of the year.
