Stiggy Racing have confirmed Leon Haslam will be their sole representative for the latest round of the World Superbike Championship in Kyalami.

With John Hopkins scheduled to make his return to competition for the Miller Motorsports Park round in just over a fortnight's time, Monza stand-in Jake Zemke will now fly home to compete in the latest round of the AMA Formula Xtreme.

It means Haslam will compete in South Africa as a sole entry, where he is looking to consolidate his fourth position in the overall standings.

Zemke finished 18th and 20th on his WSBK debut with the team last time out at Monza.
