In 2008 Nielsen joined the Melbourne Storm, becoming a regular at centre. In 2009 Nielsen was sent-off for a high tackle in the Storm's round 15 clash with the Wests Tigers. He played for Melbourne on the wing in their 2009 NRL Grand Final win against the Parramatta Eels (which was stripped from the club after their salary cap scandal). Nielsen then went on to play in Melbourne's 2010 World Club Challenge victory against English champions, the Leeds Rhinos.
On 5 May 2015, Nielsen had his contract with the Dragons terminated due to disciplinary reasons. It was alleged that a woman had made a complaint to the St George hierarchy claiming that an intoxicated Nielsen bit her on the leg on a night out on 22 March 2015. The club launched an inquiry into the complaint, and on 5 May 2015 announced their decision to terminate the players contract.[12][13]
On 25 January 2016, Nielsen returned to Australia, signing a two-year contract with South Sydney.[16] He also played in the NSW Cup for the Rabbitohs feeder club, the North Sydney Bears. Nielsen made his debut for the club in round 8, playing in the centres in the 30–8 loss to the Brisbane Broncos.
On 21 July 2017, English side Featherstone Rovers offered Nielsen a contract which he agreed to in principle but the deal fell through due to visa issues.[18] On 23 July 2017, Nielsen signed on to play with the Mackay Magpies, returning to club that he played with in 2015.[19]
On 28 March 2018, it was revealed that Nielsen had been sacked by Group 9 side Junee Diesels without playing a single game for the club. Nielsen was reportedly terminated after an alleged wild night out in Junee. Junee club president Simon Vanzanten spoke to the media saying "We don’t take it very lightly at all and if it was something that was minor everyone gets one chance, but we’ve drawn a line in the sand, "After a few things that happened with the club over the past couple of years we have come on board to make sure we have a club for my kids and for the future. We can’t put up with that sort of stuff".[20]
