Chuck Liddell (Pictures) has fallen off UFC's June 7 card in London, England, due to a badly torn hamstring, Sherdog.com confirmed Monday.

The 38-year-old Liddell (21-5) was set to fight Rashad Evans (Pictures), himself a replacement for Mauricio Rua (Pictures), at O2 Arena in the main event of UFC 85.

Multiple sources tell Sherdog.com that Sacramento, Calif.-based light heavyweight James Irvin (Pictures) could be the man to fill Liddell's large shoes, though the bout with Evans (11-0-1) has not been filled at this point.

Irvin (14-4-1) would make a quick turnaround following an eight-second knockout of Houston Alexander (Pictures) on April 2.
