In December 2009 it was announced that Witt had decided to return to rugby league, signing with Wales-based Super League club Crusaders. On 29 January, Witt scored Crusaders first points of 2010, and the first points of 2010's Super League XV with a penalty kick in their 34–6 loss to Leeds Rhinos. Midway through the Super League season, Witt was considered a top contender for player of the year. However, his season was cut short by an injury to his knee.
