Our boys know they will have to work hard."(SPEEDWAY 3)ADAM McKinna faces a race against time to be back on a bike later this season after suffering a broken bone in his neck.McKinna crashed out of Newcastle's meeting with Stoke at the weekend and he has been told he will miss the next three months at least.Diamonds boss George English said: "The first reports suggested Adam would be in a neck brace for a fortnight or a little longer but now the prognosis is worse and they tell us September at the earliest when the season will be almost over."(FIXTURES)THURSDAY JUNE 3:SKY SPORTS ELITE LEAGUE: Eastbourne v Swindon 7.45, Peterborough v Lakeside 7.30 PREMIER LEAGUE: Redcar v Newport 7.30, Sheffield v Birmingham 7.45 FRIDAY JUNE 4:SKY SPORTS ELITE LEAGUE: Lakeside v Eastbourne 8pm PREMIER LEAGUE: Scunthorpe v Newport 7.30, Somerset v Stoke 7.30, Edinburgh v Glasgow 7.30 NATIONAL LEAGUE: Weymouth v Buxton 7.15 NATIONAL TROPHY: Plymouth v Isle of Wight 7.30SATURDAY JUNE 5:PREMIER LEAGUE: Stoke v Birmingham 7.30, Workington v Newcastle 7pm PREMIER LEAGUE KO CUP 2nd leg: Rye House v Edinburgh 7pm SUNDAY JUNE 6:PREMIER LEAGUE: Glasgow v Scunthorpe 4pm, Newport v Berwick 2.30 PREMIER TROPHY SEMI-FINAL 1st leg: Newcastle v King's Lynn 6.30 NATIONAL LEAGUE FOURS: Mildenhall 5pmMONDAY JUNE 7:SKY SPORTS ELITE LEAGUE: Belle Vue v Coventry 7.30, Wolverhampton v Peterborough 7.30
