PROPS TO JAKE TMZSports.com
Caleb Plant is down to be Jake Paul's next opponent after El Gallo gets done with Julio César Chávez Jr. -- telling TMZ Sports he'd love to get in the ring soon with the former YouTuber and mix it up.
The 23-2 fighter had nothing but kind things to say about Paul while out at The Mayan in downtown Los Angeles earlier this month ... but he said if Jake really wants to throw hands and make some cash in the near future, he's all for it.
