"We understand it's a minor strain or tear to a calf muscle, we're having professionals assess it," David Higgins from promoters Duco Events said today.

"We'll take our final advice from the professionals and make a decision from there.
"No risks will be taken with what is on the line. This is part of boxing and we have to be philosophical about the situation."
The good news is if Tua vs Ustinov is postponed it will likely be for only a few weeks, according to Duco Events.
The 40-year-old Tua elaborated on his injury:
"It is what it is," he said. "From this point on it is about being smart.
"In the past I have gone into fights carrying injuries but the stakes are too high at the moment. "I have to do everything I can to make sure I heal as quickly as possible and get back to full strength as quickly as possible."
"I have had the chance to meet Alexander Ustinov in the last few days and seen the challenge that awaits me in the ring. That challenge excites me. It's going to be a great fight. But right now, I have to be smart and make sure I'm healthy going into the bout."
Although Tua hasn't fought in nearly two years, the fight with Ustinov is being publicized as a heavyweight title eliminator between two fighters at a crossroads.
A native of Belarus, the 36 year old Alexander Ustinov is ranked No. 32 in the division by BoxRec and Kubrat Pulev, now ranked in the top five, is the only fighter to have defeated him (September 2012 via 11th Round TKO).
And at 6'7½″/202 cm, Ustinov will also enjoy a major height and reach advantage over Tua (5'10″/178 cm) when they meet.
If David Tua still has a powerful left hook, the speed to unleash it in an instant, and a sturdy chin, he may present a modest, if not formidable, threat to anyone in the division.
