Rob Gronkowski ain't retired from WHOOPIN' THAT ASS ... 'cause the ex-NFL superstar tells TMZ Sports he wants a WWE fight against his "wimp" friend Mojo Rawley!!!
The 30-year-old knows his way around the ring ... he famously helped Rawley win the Andre the Giant Memorial Battle Royal at WrestleMania 33 in 2017.
So, when the ex-Patriots tight end was out in NYC promoting his partnership with CBDMedic earlier this week, we had to ask if a full-time gig with WWE was in his future.
