Even though Tom Brady's back,Rob Gronkowski says he's not ready yet to commit to playing football again ... telling TMZ Sports he's still truly undecided about his future.
Most thought the tight end would be a shoo-in to return to Tampa Bay in 2022 after his QB unretired ... but Gronk says that's just not the case -- at least not yet.
In fact, Rob says he actually avoided catching footballs at a charity event over the weekend so he wouldn't get an urge to make a decision that he might regret later.
"I knew if I started catching some passes that my head would have started turning, like, 'Oh, crap, I got to get back out on the field,'" Gronk said. "And, right now, I'm not ready to get back out on that field. I'm not ready to commit to the game of football right now."
The 32-year-old does not have a contract yet -- and he said he won't sign a new one until he's 100 percent sure he's ready to get back on the field.
As for what he's doing in the meantime -- he told us he's enjoying his offseason ... and he announced Gronk Beach is making its return this year at the NFL draft in Las Vegas later this month.
Rob says the party will happen on April 29 -- and he promised it'll be a complete rager.
After that, it appears a football decision will ensue.
