Saunders' father, in an interview, said they could have asked for a 26 ft ring (the largest is in fact 24 ft). He went on to say... "it's wrong". However, when asked what was agreed in the contract, he replied.. "I'm not sure".
20 ft rings are the standard size; I don't think Billy Joe Saunders has ever fought inside a 22 ft ring in his professional career.
