Well, Wlad did say he'd make Haye eat the first t-shirt... If he were a mug, I can imagine just when the fight is stopped he gets out one of Haye's t-shirts and wipes his feet on it and throws it at Haye afterwords or something like that But that wouldn't be Wlad really.
Wlad is far too CLASSY to pull a stunt like that, he'll help Haye onto a stretcher and ride in the back of the ambulance with him to have his glass jaw super glued back together.
