Satin says if things move according to plan, Gronk is expected to appear on "Friday Night Smackdown" in New Orleans on March 20.
Gronk LOVES pro wrestling -- and the McMahon family. Just last month, he was pictured with Triple H during Super Bowl weekend in Miami.
And, don't forget when he famously jumped in the ring to help out his pal, Mojo Rawley, at Wrestlemania 33 in 2017 -- and looked like a natural.
In fact, Gronk even told us a short time after that bout he wanted a WWE match of his own with Rawley!!
If Rob does ultimately get into the sport full-time ... he'll have no shortage of rivals -- everyone from Becky Lynch to Lio Rush and Bobby Lashley have talked smack about the 30-year-old.
As for Gronk's ability to wrestle full-time despite having no real background in the WWE world ... Rawley told us last year, "All I know is whatever he does next, or what he's doing currently, he's gonna be the best at."
Gronk famously retired from the New England Patriots back in 2019 ... finishing his career with 3 Super Bowl rings and 79 total receiving touchdowns.
