Dapper Tom Brady arrives at SoFi Stadium for ‘test run’ during Rams-Cowboys preseason game ahead of his announcing debut in Week 1

Tom Brady is in the building for the first day of his new career.

The seven-time Super Bowl champion arrived at SoFi Stadium in Los Angeles on Sunday for an exhibition game between their hometown Rams and the Dallas Cowboys.

“Tom Brady is in the building today for his test run on the FOX broadcast ahead of his Week 1 TV debut for Cowboys-Browns,” reported Nick Harris of DallasCowboys.com.

Brady was seen on the field a few hours before kickoff, chatting with host Kevin Burkhardt and billionaire Cowboys owner Jerry Jones. The California native looked dapper in a navy suit and matching pants, a polka-dot tie and brown leather shoes.

Oddly enough, Sunday’s game was broadcast on NFL Network and not Fox Sports.

It’s been a busy week for the NFL legend, who celebrated his birthday on a yacht before flying to Paris for the Olympics with his daughter Vivian and performing at a Morgan Wallen concert in Las Vegas.

Last month, Brady announced that he will approach his new career as a reporter differently than he did as a player.

During an appearance on The Pivot Podcast, tThe 47-year-old admitted he took football “too seriously” compared to other quarterbacks, most notably 28-year-old Chiefs star Patrick Mahomes.

‘When I see these young players, I see, just like Patrick [Mahomes] There at quarterback, running around, laughing, having fun, I thought, “I used to be like that. What the hell happened?” Brady said, laughing.

“I just got too serious, but again, I can only look back and think, ‘Okay, if I do it again, which I will never do again, I would be different.’ But the reality is, that can’t be done.”

While he has no plans to undo his retirement, Brady says he’s carrying that mentality into his second career in the broadcast booth.

“So you learn from it. Now, next phase of life, enjoy it a little bit more,” he explained.

After hanging up his football boots, the former quarterback has signed a lucrative 10-year, $375 million contract with Fox Sports, making him the network’s lead NFL analyst.

In addition to his long-awaited career as a TV host, Brady is a co-franchisee of several teams.

He has stakes in the WNBA’s Las Vegas Aces, the EFL’s Birmingham City FC and Major League Pickleball’s Las Vegas Night Owls. He is also bidding to become part owner of the Las Vegas Raiders.
