While some fans were skeptical that Tom Brady‘s second retirement from the NFL would stick, the league’s greatest quarterback really has hung up his cleats for good. In addition to kicking off a color commentary career for FOX Sports, Brady can now count himself as an owner, given his stake in the Las Vegas Raiders.

Brady was announced as a Raiders part-owner last May, although the NFL has yet to formally acknowledge the seven-time Super Bowl champion’s minority stake in the long-suffering franchise. Further, few people have known just how much of the Raiders really belongs to Brady — until now, that is.

What is Brady’s ownership stake in the Raiders?

Brady received some welcome news this week, as former New England Patriots teammate Richard Seymour is joining his bid to formally acquire a stake in the Raiders. Seymour‘s entry into the process has shed new light on exactly what percentage of the team the former Patriots stars are set to acquire.

According to ProFootballTalk‘s Mike Florio, Seymour, Brady, and their partners would own 10.4 percent of the Raiders — which is not an insignificant slice of the franchise. Florio further reports that the NFL’s other majority owners will bring the Seymour-Brady partnership to a vote in October, and 24 of them will have to give their approval in order to finalize the transaction.

Seymour, a Pro Football Hall of Fame inductee, split his 12-year career between the Patriots and the Raiders. The imposing defensive end won three Super Bowl titles in New England and was selected to two of his seven Pro Bowls while playing in Oakland, where the Raiders were based until 2020. Seymour reportedly had input in the franchise’s decisions to hire head coach Antonio Pierce and general manager Tom Telesco this offseason, prefacing his expected ownership stake in the franchise — which last appeared in a Super Bowl following the 2002 season.
