Brady suffered the injury in his final season with the New England Patriots and it gradually worsened during his freshman year at Tampa, according to the report.
Brady, who wasn’t on the injury report all season, underwent knee repair surgery in late February after leading the Buccaneers to a Super Bowl victory at 43.
Brady did not discuss the details of the operation, only saying it was “serious enough”.
Brady suffered an anterior cruciate ligament tear in the same knee in week 1 of the 2008 season.
Buccaneers quarterbacks coach Clyde Christensen said in June he believed Brady’s knee injury last season was a “nagging nuisance” that plagued him all season.
“I don’t think he was 100% last year,” Christensen said, relating a conversation he had with Brady the morning after the Bucs won Super Bowl LV. “His quote, or almost, was, ‘Hey, I’m going to get my knee fixed and I’m going to get better next year and you’re going to be excited about that.’ “
Brady wore a brace on his left knee during the Buccaneers Super Bowl boat parade. But wearing the corset is not uncommon for Brady, 43, who also wears it when playing golf and other recreational activities.
The seven-time Super Bowl winner has been named Super Bowl MVP for the fifth time in his career after collecting 201 yards and three touchdowns in Tampa Bay’s 31-9 win over the Kansas City Chiefs.
Brady had 4,633 yards and 40 touchdowns while leading the Bucs to an 11-5 record in the regular season.
