returning after two years away from the sport. A fight with unbeaten Alexander Ustinov was set to take place in October 2011, but Williams withdrew due to a viral infection. Williams fought the Norwegian heavyweight boxer Leif Olve Dolonen Larsen in Pabellon Municipal, Silla, Valencia, Comunidad Valenciana, Spain on Friday 2 December 2011. Williams was dropped several times by the former NFL footballer and the fight was stopped in the second round. Williams announced his retirement once again shortly afterwards, but a return to boxing was scheduled against 0–3 middleweight Marvin Meyer, leading to various hoax articles claiming that Williams was moving down to middleweight. This fight never happened, and neither did a rematch with Zoltan Petranyi for the Universal Boxing Organisation (UBO) European title, which was called off on the day of the fight after Williams was cut when he fell over in the shower. The two fighters entered the ring on fight night to apologise to the crowd for the incident. A second rescheduling of the fight, which had already been postponed from 2011 due to "personal problems" for Williams, was promised but has yet to be scheduled. Williams had two unsuccessful title challenges in September 2012, being outpointed in Finland by Janne Katajisto for the obscure Baltic Boxing Union belt and then being stopped in the 4th round against Christian Hammer in a WBO European heavyweight title fight. Williams refused to take a drugs test after the fight, claiming there was no point as he was going to retire, and that he was shot. Just days after announcing yet another retirement, Williams called out Mark Potter for a rematch of their famous clash in 2000 when Williams knocked out Potter despite having a dislocated shoulder. Potter responded saying he was very keen on the fight. The fight is likely to be unlicensed as Potter's BBBofC license was taken away after suffering a detached retina, while the BBBofC have already announced their reservations against licensing Williams. Williams later claimed he had been told to call out Potter on camera, and that he was not being serious. Once again, Williams's retirement proved to be short-lived as he fought Denis Bakhtov in Podolsk, Russia on 8 December 2012, losing by unanimous decision over 10 rounds. He fought again just 13 days later losing in a points decision against Werner Kreiskott over 8 rounds. In March 2013 he was stopped in
