"I did not agree with the decision. I thought that Jake Paul pulled it out," Porter told Babcock on the "TMZ Sports" TV show (airs weeknights on FS1), before knocking the overzealous referee's impact on the fight/scoring.

"Definitely hard to score the fight when you have a referee in there trying to control the action a little bit more than I personally felt he should've been."

Of course, 26-year-old Paul lost by split decision to 23-year-old Fury. One of the judges had Jake winning, 75-74. But, the two other judges both saw it the same way, with Fury winning on their scorecards, 76-73.

"Overall, I thought both guys did a fantastic job in terms of handling the moment, handling the ring itself, and everything that came along with it. But, overall, I thought Jake pulled it out," Porter said.

Tommy and Jake have both been criticized for not being real boxers (whatever that means) ... but Shawn says this was nothing besides a great night for the sport.

"This was a 50/50 back-and-forth match, ya just gotta appreciate it, man. Ya gotta appreciate boxing. It really was true boxing, the art."

We also asked Shawn -- who only lost four fights in his great career -- what advice he'd give Jake as he attempts to get over the first loss of his career.

"Go home, go back to Puerto Rico, get with your family, friends, people that love you, keep them around you right now, and just really decompress and get some space away from boxing right now."

Porter also talked about the hate Jake's surely receiving after the loss, advising him to steer clear of the haters.

"Boxing is a very vicious sport especially if you're misunderstood in the sport, you get a lot of people coming after you, and I'm sure he's been used to that for some time now, but exhaust yourself more? Take some time away from it all and just be with family and friends."

Now, Jake and Tommy will hammer out an agreement for a rematch ... but Shawn says we may actually see more than two fights.
