Buccaneers quarterback Tom Brady was absent from Thursday's practice and was expected to be out for at least another 10 days for undisclosed personal reasons.
The development was revealed by several NFL reporters, including NFL Network's Ian Rapoport, who noted that the future Hall of Famer "is fine" and his absence was not related to football.

Buccaneers officials were "on board" with Brady's extended nonattendance, Rapoport added.
Head coach Todd Bowles later told reporters that Brady would be out at least through the Buccaneers' second preseason game against the Tennessee Titans, scheduled for Aug. 20.
However, Bowles declined to firmly commit to having Brady back in the fold for Tampa Bay's Week 1 contest against the Dallas Cowboys, scheduled for Sept. 11 on Sunday Night Football. Brady's absence was planned and had been discussed before camp started, Bowles added.
Brady, 45, has had an eventful year, to say the least.
He briefly retired during the offseason before announcing his comeback, sparking wild speculation about his future in Tampa Bay.
Subsequent reports indicating that he had plotted a move to the Dolphins seemed to be confirmed when Miami was fined and docked draft picks for tampering both with Brady as well as former Saints head coach Sean Payton.
As well, former head coach Bruce Arians stepped down, being replaced by Bowles, who previously served as defensive coordinator under Arians. Brady and Arians were long reported to not see eye-to-eye.
