Bryan Staring has been forced to delay his World Superbike debut with the IRON BRAIN Grillini Kawasaki team after injuring his arm at Donington Park.

The Australian - who has come into the Italian team to replace Michel Fabrizio - has been contending with an arm injury throughout the weekend, but after struggling with the ZX-10R on the first day of competition, the decision was taken to focus on full fitness for Sepang.

Meanwhile, Geoff May will also miss the two races as his Erik Buell Racing team struggle with technical issues on his 1190 RX Superbike.
