As Boxingtalk first reported, a heavyweight unification bout between IBF and IBO champion Wladimir Klitschko and WBO champion Sultan Ibragimov is in the works and looking good for February 23. However, the location of the bout remains up in the air. When we first broke the fight appeared to be headed to the Garden, but as this goes to print, BT understands Moscow and Germany are still in the running.
