Brave Dane Kenneth Bjerre will battle through the pain to keep his early-series Speedway Grand Prix challenge alive this evening.

The King's Lynn Stars rider last night climbed aboard a bike for the first time since breaking his collarbone on April 30 against Leicester Lions. But after that practice session it is back to business tonight when the heat leader gets out on Finland's Tampere circuit in the third round of the 2014 world championship.

Bjerre said: 'The doctor told me I could ride but that he'd prefer me to have another week off. My collarbone is in place, although if I crash it could be a problem I guess.

'But it's the world championship and that's the risk I'm taking this week. When I'm not moving the arm it's fine. I haven't lifted anything with the arm (left one), so it's maybe a little bit weak. But my arm and collarbone doesn't really hurt much. It was my neck and shoulder that hurt more as I whipped into the floor.

'I did a bit of ligament damage to my shoulder but that just needs settling down a bit. I'll be on painkillers though just to make sure if I do feel any pain. But the adrenaline should kick in when I'm riding. I'm sure I'll feel it between races but when I'm riding it'll be on a big track, not like an Eastbourne or a Lakeside where you have to turn hard, so I'm hoping I'll be ok.'

Bjerre sits 11th with 15 points after two rounds, just one point and place behind his fellow Lynn team-mate Niels-Kristian Iversen – who won the first round of the Danish final this week.

His injured countryman opted to sit out the national event to allow himself more rest before this evening's GP and admits it was a pretty easy decision to make.

'I wanted to win the Danish final but I had a choice to make and of course I went for the GP,' he said.

'It's a bit of the gamble but the doctor said it's my choice. When it's your team, you can get a guest, but no-one else is going to score points for you in the world championship.'

Bjerre reached the semi-final of the opening round while world number three Iversen did the same last time out.

But both are already a fair way behind leader, Polish superstar Krzysztof Kasprzak – who has a haul of 35 – and will be keen to try and reduce that deficit with him missing out through injury.
