Tom Brady completes Raider's investment but cannot play owing to NFL loophole.

Due to NFL rules, Tom Brady's return to the field is unlikely as he nears ownership.

Sports Illustrated reports that Brady's minority stake in the Raiders has been approved. Brady owns WNBA team Las Vegas Aces with Raiders owner Mark Davis.

Any investment will likely end talks of Brady returning to the field.

Part-owners cannot engage in a "dual role" without authorization from the other 31 NFL teams, therefore it seems unlikely that all would vote for Brady to return.

ESPN reports that Brady will be a "passive" investor with no control over team or business choices and will not play for the Raiders. 

Fox's approval won't influence his 10-year TV deal starting in 2024. 

Before his investment, the Raiders seemed like a good fit for Brady. The Raiders' coach, 

Josh McDaniels, was Brady's offensive coordinator with the Patriots, and Jimmy Garoppolo's injuries have caused problems.

Yankees might assign $25M player to simplify infield.
