Tom Brady reversed his retirement decision of a month ago in an overnight social media post, declaring that he will return to play for his 23rd season and will do so "in Tampa".
The Tampa Bay Buccaneers, whose defence of the Vince Lombardi Trophy was ended by the Los Angeles Rams in the divisional round of last season's playoffs, have been trimmed to 9/1 to win Super Bowl LVII on news of Brady's U-turn.
He wrote: "These past two months I've realised my place is still on the field and not in the stands. That time will come. But it's not now.
"I love my team-mates, and I love my supportive family. They make it all possible. I'm coming back for my 23rd season in Tampa. Unfinished business LFG," he concluded.
The 44-year-old's retirement lasted 40 days, during which time several unsubstantiated rumours emerged about whether he might make a comeback in another team's uniform.
He remains under contract with Tampa Bay, "but it's a placeholder year worth about $10.4million" reported NFL Network's Tom Pelissero, who expects the Bucs to simply add another year to Brady's contract in which his earnings would be commensurate to the NFL's other top quarterbacks.
The Bucs ranked second in the NFL with 30.1 points per game last season as Brady led the league in passing yards (5,316) and touchdowns (43).
"Total excitement," was the initial reaction that Buccaneers head coach Bruce Arians texted to NFL Network Insider Ian Rapoport on Sunday.
Other pieces are already falling into place for the Bucs, who subsequently locked up center Ryan Jensen on a new three-year, $39million deal that keeps him from becoming a free agent.
