Tom Brady almost joined the Las Vegas Raiders in 2020 after a deal was brokered by UFC chief Dana White – only for Jon Gruden to walk away from negotiations in the final stages.

Elite quarterback and perennial winner Brady entered the 2020 season as a free agent, despite boasting six Super Bowl titles and nine AFC championships.

The Raiders, aided by the involvement of White, were reportedly set to swoop for the former New England Patriots star before the Tampa Bay Buccaneers secured a deal for one of NFL's most coveted names.

Brady would throw 4,633 passing yards and 40 touchdown passes as Tampa Bay won eight consecutive games en route to his seventh Super Bowl title in his maiden Buccaneers term.

The intervention of then-Raiders coach Gruden proved the stumbling point as Brady and colleague Rob Gronkowski, who was contracted to the Patriots at the time, ended up playing for Tampa Bay.

"I worked to put that deal together for Brady and Gronk to come to the Raiders," White said on ESPN during Saturday's UFC 278 coverage after being convinced by Gronkowski to tell the story.

"It was almost a done deal. And at the last minute, Gruden blew the deal up and said that he didn't want him and all hell broke loose, man. It was crazy.

"And Brady was already looking at houses. It wasn't said yet that Gronk was going to be coming. So Las Vegas would have had Brady and Gronk the year that the Bucs won the Super Bowl, except Gruden blew the deal up."

While Brady was said to have been a long-term target of the Raiders should he become a free agent, White believes the Las Vegas franchise could have comfortably secured Gronkowski as well.

Neither arrived and duly went on to Super Bowl success with the Buccaneers, with Gruden resigning as Raiders coach in October 2021 – yet Gronkowski has no regrets.

"I'm glad it did not go through," Gronkowski added. "It all worked out for the best, man. I'm glad we went to Tampa, man. It just worked out. I love that place."

Tampa Bay are preparing for their third campaign with Brady as their quarterback, though the veteran has not appeared at their training camp in pre-season.
