When Alexander Ustinov ended his fight - his only loss - to tough Bulgarian Kubrat Pulev last year, he did so by sinking to one knee and taking the count.
He hadn't taken a single telling blow. The YouTube footage shows him waiting for the referee to do his work. It looked like a surrender, a signal that if a fit and committed David Tua were to attack with those renowned heavy shots of his in Hamilton tomorrow night, the giant Belarusian's nerve could come under question.
But now it has been revealed that a punch from the unbeaten and highly regarded Pulev damaged Ustinov's eardrum and, disoriented and in pain, he sank to one knee to end the fight.
Duco Events boss David Higgins says Ustinov's handlers confirmed the eardrum problem and, if true, it means Tua has an even tougher job to get past the 2.03m, 132kg heavyweight.
The New Zealand TAB has Tua as favourite, but that is clearly based on the betting actions of the biased and maybe hopeful local market. Ustinov is the kind of fighter with whom Tua has had problems. Only 1.78m, Tua has had difficulty with tall boxers with efficient jabs, who can score and move, circling away from his damaging left hook and tying him up when he moves in close.
