Departing Kawasaki rider Tom Sykes will miss this week's Portimao WorldSBK test after suffering a training injury.

The Huddersfield rider been diagnosed with a rupture of the anterior fibular talus ligament and bone delamination in the insertion of the ligament in the fibula bone. He is hoping to be fit to race in the next round of the championship, in mid-September.

“It is a shame to miss this test because we have had a big gap in the season. I have been doing a lot of fitness training during the break and the results were very good," said Sykes.

"I was feeling very strong. But with this injury I am going to have to sit out the test, as I do now want to push it. It is a shame because Marcel and the boys had a good programme for the tests, so that we could finish the season strongly.

"We were going to play with the package because we would have a lot of track time to do so. The focus now is to try and be fit for the next race.”
