A horror crash in heat 15 marred a great meeting at the Norfolk Arena tonight.

The Stars, who needed a heat advantage in the nominated race, looked set to get it as Rory Schlein dived up the inside of Piotr Swiderski to move into second behind Tai Woffinden. But he was excluded – much to the anger of Lynn chief Buster Chapman and team boss Rob Lyon who said the Pole was out of control down the back straight – as the reason for the main cause of the accident which saw Swiderski hit the deck.

But worse was yet to follow as Peter Karlsson rode straight over the top of his team-mate and flew into the deck with a thud which stunned Saddlebow Road into silence. The popular 43-year-old came off worse from the shocking spill and was taken by ambulance to the town's Queen Elizabeth Hospital with suspected lower back injuries.

In the end, the fact that Lynn got just two league points – while their play-off chasing rivals went home with one – seemed pretty irrelevant.

Lynn guest Woffinden had started the night by blasting to a tapes to flag victory in heat one. But that was as good as it got for the home faithful early on with Lakeside opening up a daunting eight-point lead. .

Some cracking action was interuppted by Davey Watt hitting the deck, which forced Rory Schlein off in the process. The Australian showed his bravery by getting up and winning the re-run though to prove that Lyon's men were not in the mood for rolling over. Yet a couple more 4-2 reverses saw Lynn up against it.

That was until Nicklas Porsing showed why the Stars signed him in the first place. The Young Dane ripped away from the tapes and, shepherded home by Schlein, helped pick up the Stars first heat advantage of the night – a huge 5-1.

Lyon drafted the winner back in as reserve-switch in the next outing and it was Groundhog Day as Porsing judged the tapes coming up superbly to win from start to finish. This time, Kozza Smith followed him home to make things all square.

The excitement, and unexpected nature of the comeback, reached fever pitch levels when Richie Worrall and Mads Korneliussen completed the hat-trick in the ninth to put Lynn in front for the first time.

The Stars had come to life at the right time and their gritty display was now being supplemented by a touch of class and confidence – all gained from Porsing's double-salvo. However, their eight-point lead was pegged back slightly leaving it all to play for in the last one – which was shared 3-3 in the re-run.
