Rob Gronkowski told us it was happening, and now it's official -- the superstar tight end has re-signed with the Tampa Bay Buccaneers with a deal worth up to $10 million!!!
Remember, 31-year-old Gronk told TMZ Sports just last week he wasn't handing in his retirement papers just yet ... saying he was ready to run it back as Tom Brady and Co. try to repeat as Super Bowl champions.
"I'm back, man!" Gronk told us. "I will be back playing football, man. I love the game of football. I loved playing last year. I had a great time."
Gronk wasted no time with free agency kicking off this week ... agreeing to a 1-year, $10 milli deal on Monday.
Rob was solid in 2020 -- his first season back since leaving the game in 2018 -- putting up more than 600 yards and 7 TDs.
