Shamrock, meanwhile, after a brief retirement, was rumored to face Michael Bisping at UFC 75 but was ultimately released from his UFC contract. Shamrock returned to fighting in 2008 and lost to Robert Berry via technical knockout. He then defeated Ross Clifton on February 13, 2009 via submission and was scheduled to face former WWE wrestler Bobby Lashley in an MMA bout, but tested positive for steroids after the Clifton fight in which he served a one year suspension. He then lost his next to bout to Pedro Rizzo via TKO. He would then go on to defeat Johnathan Ivey via unanimous decision and lose to Mike Bourke via technical knockout due to a leg injury. Shamrock was to have competed against Boxing's Heavyweight Champion James Toney in a specialized MMA bout in Fall 2011, but it did not materialize. Since his return, Shamrock has received much criticism for fighting too far past his prime and has currently won 3 out of his last 12 fights.
