SWINDON Robins heat leader Nick Morris will miss next Thursday's SGB Premiership clash with champions Wolverhampton Wolves at the Abbey Stadium after suffering concussion in a racing spill last night.

Aussie ace Morris, riding for his Championship side Berwick Bandits, was knocked unconscious after a heat one collision during the northern side's 53-39 defeat at Peterborough Panthers at the East of England Arena.

Morris received lengthy treatment before being taken to hospital and, having been adjudged to have suffered concussion, must now stand down for a mandatory nine-day period under Speedway Control Bureau (SCB) regulations for riders aged over the age of 20.

That rules the 23-year-old out of Swindon's Thursday appointment against the Wolves, while his participation for Australia in Event One of the Speedway World Cup at King's Lynn on July 1 may also be in doubt.

Berwick manager Gary Havelock said: “I can't believe we're going to be without our brilliant number one Nick Morris for at least nine days. It's sickening, totally sickening.''

There was however, some better news for Swindon Robins supporters, with skipper Jason Doyle set to take part in tonight's Speedway Grand Prix in Denmark, despite breaking three bones in his right foot after a crash while riding for his Polish side Zielona Gora earlier this week.

Doyle, currently second in the overall Grand Prix standings, had his foot passed fit after a practice session in Horsens yesterday, following last Sunday's crash with former Swindon rider Adrian Miedzinski in Zielona Gora's 46-44 win at Torun.

The Australian rider underwent surgery in Torun 24 hours later to stabilise the injury and insisted he was ready to race this evening.

Posting on Facebook, Doyle wrote: “Thank you to all my supporters who were concerned about my injuries sustained in the incident in Torun on Sunday night.

“Firstly I would like to thank Dr Damian Janiszewski and his team from Torun for all their hard work. They all worked so hard to give me the best chance of racing this Saturday night in Horsens. Dr Damian and his team operated on my foot at 11.30pm on Monday night in Torun Hospital.

“I am sorry to all concerned, but I wanted to keep a low profile of my injuries so I could concentrate on making the Horsens GP. I didn't want the media to blow this situation out of proportion.

“I broke three bones in my right foot when it went into the other rider’s front wheel. I have now got three plates and 14 screws in there to make the bones stronger so I can race tomorrow (Saturday) night.

“Today (Friday) in Horsens was a must practice. This is a requirement by the FIM to show that any rider with an injury is 100 per cent capable of racing a speedway bike and to show they are safe to compete against their competitors.''
