Mike Tyson's trainer has dismissed claims the heavyweight icon's health is at risk when he fights Jake Paul.
The former champion will return to the ring aged 58 and face YouTube star Paul in a showdown on July 20 in Texas.
A 31-year age gap will exist between the pair by the time of fight night, which has led to widespread criticism of the encounter.
Paul and Tyson are expected to fight under traditional rules, with rumours of headgear being in use dismissed.
The fight could even be sanctioned as a professional bout, which would be Tyson's first since retirement after losing to Kevin McBride in 2005.
After a warning from a doctor over potential brain damage surfaced, Tyson's trainer Rafael Cordeiro has insisted that 'Iron Mike' is in perfect condition to compete.

"When he steps inside the ring he knows what to do. It’s not something new for Mike, and this fight is no different.
"He works hard every single day to go in there and try to knock Jake out from the beginning to the end. He’s going to prove that in July.
