Mark first played rugby league in his native South Africa in 1992, including two test matches against the CIS (later Russia). He joined London Crusaders in March 1993, and was an important member of the marvellous 1993-94 side, led by Sam Stewart and coached by Tony Gordon. He finished that season as the top try-scorer in British rugby league with 43, including a hat-trick at Old Trafford in the Second Division Premiership Final. He stayed with the club for one more season, but before Super League started moved on to Workington Town. He then played for Hull, Salford and Leigh before returning to South Africa. He also played for his country in the 1995 and 2000 World Cups.
