An N.F.L. investigation has found that “it is more probable than not” that New England Patriots personnel intentionally deflated footballs to gain an advantage in the A.F.C. championship game last season, and that Tom Brady, the Super Bowl most valuable player, was aware of it.
No penalties have been announced.
The long-awaited report into so-called deflategate, released on Wednesday, concluded that it was probable that Patriots personnel were “involved in a deliberate effort to circumvent the rules.”
The report said that Jim McNally, a locker room attendant, and John Jastremski, an equipment assistant, released air from the footballs.
