Tampa Bay Bucs -- Shout-out from Beyonce ... For Letting Jay Z Train In Team Gym

The Tampa Bay Buccaneers got a "special thanks" from Beyonce at the end of her "Lemonade" special this weekend ... and TMZ Sports has learned it all has to do with a favor the team did for Jay Z.

We didn't notice any players in the special ... or stadium shots or any other obvious Bucs references -- so, we asked the team ... why did Bey shout-out TB?

A rep for the team told us, "We actually were not involved with Lemonade, it was actually just a thank you for allowing Jay-Z to come and work out at our facilities during their time here in Tampa as they were preparing for the start of her tour."

Turns out, Jay got his pump on at the Bucs facility earlier this month ... and the team was so happy to have him, QB Jameis Winston presented Jay with his own custom Bucs jersey.

"It's an honor to meet you," Winston told Jay at the time. He even offered to take Hov out to the field to throw the ball around ... though it's unclear if that ever happened.

Still, pretty cool to get a shout-out from Bey.
