Gunning For Tank Davis Rematch

"Unfinished business."

That's what boxing star Rolly Romero says he has with Gervonta "Tank" Davis ... after losing to the undefeated superstar in May 2022 by 6th round knockout.

TMZ Sports talked to 28-year-old Romero, 14-1 (the only loss being Tank), ahead of his mandatory fight with Ismael Barroso (24-3-2, 22 KOs) on May 13 on Showtime ... a fight Rolly knows he needs to win in order to earn the chance to run things back with Davis.

Of course, Davis is coming off an impressive win over Ryan Garcia ... and many fans, fellow fighters, and experts believe Gervonta is now the face of the sport.
