If Mike Tyson is serious about a comeback -- and wants an exhibition fight -- HOW ABOUT A REMATCH WITH EVANDER HOLYFIELD!!
That's what boxing star Shawn Porter wants to see ... telling TMZ Sports, "To see him in the ring in an exhibition against Holyfield would be amazing."
53-year-old Iron Mike set the boxing world on fire this week after posting new training footage ... and even though the clip is short, he looks as explosive as ever.
"Just to see that small combination that he threw with the velocity he was throwing it at, and again the integrity that came along with it was very special for me," Porter explained.
