Injury-hit Eastbourne Eagles will use Edward Kennett as a guest replacement for Joonas Kylmakorpi at home to Wolverhampton on Saturday.
Kylmakorpi, who suffered neck and shoulder injuries in a track crash in Poland on Sunday, has returned to Sweden for treatment.
And with Lewis Bridger also set to miss the meeting, the Lifestyle Eagles will face a tough challenge from a Wolverhampton side who rarely disappoint around the Arlington circuit.
Team manager Trevor Geer said, “Naturally it is a big blow to lose our No 1 to injury again, although Edward Kennet will be an excellent replacement.
“It is going to be tough against Wolves in what really is a must win match for us.”
After the Elite League match, Arlington hosts the Wessex Marine 125cc British Championship.
Twelve up and coming young riders will take part in 12 heats with the top four going on to the final to see who will be crowned champion.
Henry Atkins from Exeter will be back to defend the title he won a year ago but is sure to face a tough challenge, especially from Karl Bickley and Tom Brennan who top scored at Eastbourne during the 125cc support races at round four of the British Youth Championships.
Co-promoter Mike Bellerby said, “The professionalism of the boys who took part in the youth championships was a joy to behold.
“I hope as many fans as possible will watch this one-off championship and give the lads as much support as they can.”
With Elite League racing and a British championship it is going to be a great Saturday at Arlington but to top it off, the Eagles’ 100 Club is staging a spectacular triple draw to turn the evening into a spectacular super Saturday.
The 100 Club raises money to help keep speedway running at Eastbourne. Now in its third year, it has raised thousands of pounds with a current prize fund for each draw of £980.
Bellerby added, “Wolves are always one of the most attractive visitors to Sussex. Add to that a British championship and a super 100 Club draw and we are set for a superb night at Arlington.”
