"Obviously I was looking forward to the Leben fight but I guess it wasn't to be,” said Bisping. "You have to respect Jason Day for stepping in on even shorter notice than myself. I am looking forward to really putting on a great performance in London."

Leben turned himself in to Clackamas County officials in Oregon last week in response to a probation violation on a 2005 DUI conviction. Leben was in the process of completing the terms of his probation when he moved from Oregon to Hawaii last year. Attempts to complete these terms in Hawaii were unsuccessful, leading to Leben’s decision to voluntarily turn himself in. On Thursday, he was sentenced to 35 days in jail. With time served, Leben will be released in late May, not leaving sufficient time to prepare for the Bisping bout.
