at the Tropicana Casino and Resort in Atlantic City in a bid to promote David Tua's career in the United States. At 38 years old, Monte Barrett (34-9, 20 KOs) was viewed by some as an easy opponent for Tua as he had lost his previous three fights. The match was a controversial draw with Tua being knocked down for the first time in his professional career late in the 12th round. Tua fought Demetrice King on 19 March 2011. Tua defeated King by unanimous decision with the scores of 100–91, 100–91, and 100–90. Tua's rematch against Monte Barrett on 13 August 2011 resulted in a unanimous points decision going in favour of Barrett. The judges scored the bout 113–112, 115–112, and 115–112. In December 2011, it emerged that Monte Barrett tested positive for banned stimulant methylhexanamine following a urine test after his 13 August points decision over Tua. Tua's lawyer, Blair Edwards, called for action against the 40-year-old New Yorker requesting the return of Tua's WBO Asia-Pacific and Oriental titles and the restoration of ranking points. 2013 comeback and retirement In June 2013 it was confirmed that Tua was once again getting back into the ring. Belarusian Alexander Ustinov defeated him by unanimous points decision, following which he announced his retirement from professional boxing. Ringside Report were mixed in their evaluation of his career, referring to him as "one of the best heavyweights never to win a world title". Outside the ring On 10 October 1992 Tua appeared on the New Zealand version of the gameshow Wheel of Fortune. He had asked for an "O for Olsen" (possibly a reference to Olsen Filipaina) but this was heard by some (and widely reported) as "O for awesome". He requested "P" when buying a vowel on the same episode. He was also heard to ask if he could buy a "constonant" during the same show. From 1992 to 2003, Tua was managed by former boxer Kevin Barry, who also trained him from 2001. But in 2003, Tua ended his business relationship with Barry and financial manager Martin Pugh. Though Barry accepted his dismissal as trainer, he resisted Tua's decision to end their contract, which still had two years to go. In 2004, Tua's accountant learned that the boxer's finances with his boxing company, Tuaman Inc. Ltd., were tangled with company expenses; Tua no longer has most of his $NZ 20 million
