INJURED Pirates star Lukas Dryml has flown home to the Czech Republic to get treatment on his broken ankle.

The 22-year-old World number 10 was taken to Poole Hospital on Sunday after he had crashed into the safety fence at Poole during the 2004 Grand Prix qualifiers final.

Dryml broke his talus bone, which joins the ankle to his leg, in the track spill after he was in collision with Tomas Topinka and Peter Karlsson going into the first bend.

And he could be sidelined for a month to six weeks.

It was a real horror smash, probably the worst on the Wimborne Road circuit for eight years or more.

Dryml and Karlsson could not get off their machines as they sped at full speed towards the safety fence.

And the Czech Republic international was knocked unconscious for the second time in a month as he careered head first into the barrier along with his bike.

Dryml, who had also been unconscious after a track spill in Krsko, Slovenia, last month, was given oxygen while he was on the track.

He recovered enough to be stretchered into an ambulance but had to withdraw from the meeting.

It is believed Dryml spent a night in Poole Hospital before he left yesterday and flew to his homeland with his brother and fellow rider Ales and their father Ales senior.

Pirates co-promoter Matt Ford said: "Lukas has gone home. Doctors have plastered his ankle and he has gone back to the Czech Republic. They wanted to pin the ankle but Lukas' father felt it would be better if they went home to get treatment.

"He wants it to be done in the Czech Republic where I believe one of Lukas' uncles is a doctor, so it makes sense for them to do that.

"It is unconfirmed, because nobody has been able to have a proper chat with Lukas, but it seems he could be out for four to six weeks, although I stress that is unconfirmed."

The injury puts Lukas' World Championship Grand Prix status in serious jeopardy as he will surely be sidelined for the Scandinavian Grand Prix in Gothenburg on Saturday.

Lukas currently lies sixth in the overall Grand Prix standings but only eight points ahead of 10th-placed Scott Nicholls with four rounds to go.

Only the top 10 are guaranteed an automatic place in next year's series, so if Dryml was to miss any other rounds, he might not make the cut.
