Swan Yamaha's Noriyuki Haga says his broken collarbone is showing no signs of improvement as there has been little time in between race to rest the offending bone.

The Samurai of Slide was injured in a crash at Cadwell Park and hasn't missed a round even though he is in a lot of discomfort with it. He will race again at Silverstone at a track he knows well from his WSBK days.

“At Assen we found a good direction with the setting and we feel positive that this could work at Silverstone too. I like this track as before in World Superbike I have had good results there and know the track well. My shoulder has not had time to improve any more as there is little time between races but I still try hard to get podiums," said Haga.
