Frank Gore could be making a career for himself in the boxing ring -- 'cause the ex-NFL Pro Bowler tells TMZ Sports he's open to taking a boxing match against Jake Paul!!
The 38-year-old is fighting Deron Williams on the undercard of the YouTuber's highly-anticipated match against Tommy Fury ... and Jake previously told us he's down to take the winner of the battle of the NBA and NFL stars.
We spoke with Gore right before his press conference leading up to the Dec. 18 event ... and while he says he's focused on taking care of DW, he admits he's interested in taking a future fight against the Problem Child.
"I'm with it," Gore said. "I wanna win this Dec. 18 and if it's time to go that me and Jake Paul can get in there, I'm with it."
As for his current fight against Williams, Gore says he's been boxing since 2005, so he's got plenty of experience leading up to stepping in the ring.
"I do love the sport and I respect the guys who box, man, because it's totally different."
