Bruce Arians has stepped down as head coach of the Tampa Bay Buccaneers with Todd Bowles replacing him in the position.

Arians told ESPN he doesn't see it as a retirement. "No, moving to the front office," he said in a text message. "I'm still working."

His new job title will be senior football consultant.

Arians went 31-18 (.633) in three seasons in Tampa Bay.

Brady, in an Instagram post Wednesday night, said Arians was a major part of his decision to play for Tampa Bay and that he'll be "forever grateful."

"You are an incredible man and coach, and it was a privilege to play for you," Brady wrote. "You are a true NFL legend and pioneer for all the work you have done to make the league more diverse and inclusive. Smart, tough, and loyal are a few of the words to describe your style. I will always remember the conversations we had when you recruited me two years ago and all of the things we discussed came true."

In his statement, Arians said that he "really began thinking about my personal transition plan earlier this offseason."
