Anthony Joshua looks likely to face Oleksandr Usyk next, now that Deontay Wilder's successful arbitation appears to have put him ahead of the London 2012 Olympian for a fight with WBC champion Tyson Fury.
And Cuban veteran Luis Ortiz has volunteered his services to help the WBA, WBO and IBF titleholder for what could be one of his most challenging encounters to date.
Wilder vs. Fury 3 appears to be heading towards a July 24 date, and if the two British heavyweight kingpins are to keep hold of all the gold and resume their unification talks for later in the year, "AJ" will need to handle his WBO mandatory business in the interim.
Ortiz told Sky Sports that he is ready and willing to work with Joshua and his team while he waits for an in-ring assignment of his own.
"As far as for Joshua, I'd go help him get ready, but Usyk shouldn't be a problem for Joshua," Cuba's two-time world title challenger told Sky Sports.
"But then again it's boxing and at this level every heavyweight is a problem."
Joshua has sparred with a variety of partners over the years, and training camp manager David Ghansa told Sky how fighters are selected to spar with Joshua.
"What people don't realise about sourcing sparring partners is that you will never find a carbon copy," Ghansa said shortly before Joshua's most recent win in December against Kubrat Pulev.
"We look for the height, the type of shots they throw, and we try to piece together a puzzle. Sometimes, you also have to throw in a wild card.
"Lots of heavyweights reply and say: 'Thanks for the opportunity but I want to fight the champ, not spar him!'
"AJ knows sparring is about preparation, not trying to hurt anybody. But they are fighters so it can get heated."
