William Dunlop has withdrawn from racing in this week's Isle of Man TT.
The Ballymoney rider crashed during the first Superstock race at the recent North West 200 and has now reluctantly pulled out of racing in the TT, citing 'personal reasons'.
He had taken part in two evenings of practice at the TT and clocked 125.197mph on Monday evening.
Dunlop will now return home from the Isle of Man before making a decision on when to return.
“This is a very difficult decision and not one I have taken lightly, I can only apologise to the team and all of our sponsors but I believe that continuing would be the wrong decision and would not give a true account of either myself or the team,” he said.
“I would like to thank Tim especially for how understanding and supportive he has been over the past few weeks, I obviously feel like I have let him and the team down but they have stood by me throughout. I am going to head home and take some time to recuperate before making a decision on when I will be back on the Temple Yamahas.”
Dunlop had sustained an injury during a crash at the recent NW200. He highsided from his Yamaha R1 at Church corner during Thursday's Superstock race on the north coast. While a medical examination showed there were no broken bones, it did reveal heavy bruising to his back. He withdrew from Saturday's races at the NW200.
Team boss Tim Martin is hopeful Dunlop could return 'after a few weeks'.
He said: “Obviously this is extremely disappointing for us as a team and for me personally as I have been looking forward to working with William at the TT for some time. There is no race in the world however where having 100% focus and commitment is more important so it is the correct decision in the end for William.
"Hopefully after a few weeks off he will come back stronger, we all know what a natural talent he is so having a fit and well William back to fight for wins at the Ulster Grand Prix is now our focus.”
