Middleweight 15 rds
Both men are freaks for the weight.Extremely strong.But Sibson is a better boxer.Hammering his jab to throw his combinations off of.
Roldan is strong with a good chin but I don't think he can last 15 rds.
Sibson with a stoppage in the 14th rd.

i fancy Roldan here. When on form like v Animal Fletcher and Kinchen he was a tearsome proposition

Roldán KO10. Sibson is technically better but he didn’t have the punch to stop Roldán relentlessly coming forward and winging shots and one of Roldan’s right hands would take him out, IMO

Roldan KO 8
