Rob Gronkowski and the Tampa Bay Buccaneers are stepping up BIG for a local high school’s football program … joining forces to replace the team’s equipment and storage shed after a tragic fire.

A blaze broke out on Blake High School’s campus in Tampa last month … with an estimated $15k-worth of supplies destroyed, according to tampabay.com.

The team said it would be nearly impossible to replace all the equipment in time to prepare for the 2020 season … saying it simply isn’t in the school’s budget.

But, there’s GREAT news for the Yellow Jackets — the 31-year-old tight end and the Bucs are teaming up to get the program back on its feet … with Gronk announcing their decision to help out in a WWE promo-style video on Instagram.

“Hey everyone, last week we heard about an unfortunate incident in Tampa where a fire burned down a high school storage shed full of their team’s football equipment,” Gronk says in the vid. “Sadly, they lost it all.”

“Well, the Gronk Nation Youth Foundation and my new team, the Tampa Bay Buccaneers, are all about helping youth reach their full potential.”

“So, we’re gonna do just that. To the Blake High School Yellow Jackets, you’re getting a brand new storage unit and new football equipment to replace everything that was lost.”

Gronk gives the team a bit of encouragement … and even hints he may hit up a practice with his Bucs teammates.

Props to all involved!!
