By David Martin Britain's top 1500 metres runner, Michael East, has been ruled out of next month's European Championships in Gothenburg because of injury.
A combination of Achilles and hamstring injuries meant East was unable to defend his Commonwealth Games title in Melbourne in March.
The 28-year-old, who has only one race under his belt this summer, has confirmed he is not ready to challenge for selection at this weekend's Norwich Union European trials in Manchester.
"The problem I've got now is similar and in the same area of the hamstring where it was before," said East who finished seventh in last month's British Grand Prix.
"I didn't do well at Gateshead because I kept thinking about it - every-thing's now up in the air and I'm at a loose end.
"Everybody said I would be all right and said I only needed to blow away the cobwebs but I'm having to make decisions about my training from day to day and that's not a good thing.
"When I started my season's preparations, I was running pretty well but then the new injury flared up in one of the tendons in my knee.
"The problem is that when I increased my speed work, which is essential at this time of the year, it made things worse and inflamed my knee. It was also causing more pain in the back of the hamstring and occurring almost every single time that I ran."
However East, who finished sixth on his Europ ean Championships debut four years ago only a fortnight after winning his Commonwealth gold medal in Manchester, added: "Watch this space. I am hoping to compete again this season but, if I do, I must be able to stay focused on racing rather than worry about the injury."
East holds the qualifying standard for the trip to Sweden and a top-two placing in Manchester would have gained him automatic selection. n Liu Xiang made the 110m world record his own property at Tuesday's Lausanne Super Grand Prix when he won in 12.88 seconds.
The Chinese star was previously joint holder with Great Britain's Colin Jackson after running 12.91 seconds in Athens two years ago to win the Olympic gold medal.
Jackson set his mark at the world championships in Stuttgart in 1993 but will now have to hand over the record to Liu who celebrates his 23rd birthday today.
