Klitschko wants July date for Haye bout

Wladimir Klitschko has challenged David Haye to face him in a potential heavyweight unification bout on July 2.

The Germany-based Ukrainian will take on Dereck Chisora for his IBF and WBO titles in a rescheduled fight in April, which means WBA champion Haye must also take on the mandatory challenger for his title, Ruslan Chagaev of Uzbekistan, before any fight with Klitschko can take place.
