Jake Paul is doubling down on his claim he hooked up with Bellator fighter Dillon Danis' GF ... and he tells TMZ Sports he WILL take their beef to the ring ... just not yet.
So, a bit of a crash course here -- 22-year-old Jake first called out Danis last year, saying he'd beat his ass in a boxing match because his "striking is super weak."
The 2 have traded insults ever since ... and Jake recently went to IG to tell Danis to "ask savannah about the time we hooked up," .
