The Ultimate Fighting Championship on Friday announced that Jason Day will step in to replace Chris Leben in a proposed bout with Michael Bisping on June 7 at UFC 85 in London.

Leben recently turned himself in to authorities in Oregon for a violation of his probation stemming from a past DUI arrest. He was sentenced on Thursday to 35 days in jail, effectively removing him from the bout against Bisping.

Day most recently competed on the UFC 83 event in Montreal, stopping Alan Belcher in the first round. Bisping also competed in Montreal, defeating Charles McCarthy, when the American Top Team fighter was unable to answer the bell for the second round.

Day and Bisping will compete as part of the main card at the O2 Arena, which is headlined by a bout between former UFC welterweight champion Matt Hughes and fellow contender Thiago Alves. The event is scheduled to include 13 bouts in total, the most of any UFC event since the 1990s.
