A crash in Sunday warm-up forced Jack out of the Austrian Grand Prix.

Jack has been forced to miss Sunday’s Austrian Grand Prix at the Red Bull Ring, after a crash in Sunday morning warm-up left him with hairline fractures in his back and to his right wrist.

The Assen Grand Prix winner was on an out lap in Sunday morning warm-up when he clipped the inside kerb coming out of Turn 8, falling in a fast crash that saw him tumble through the gravel. Jack was winded and bruised and took an impact to his chest, and was taken to nearby Leoben Hospital for checks. He was then declared unfit to race by the circuit medical team and was forced to sit out his second GP this year, after missing Austin in April after aggravating his off-season leg injury.

The race in Austria at the Red Bull Ring, the first at the circuit for 19 years, was won by Ducati’s Andrea Iannone, who became the second maiden MotoGP race-winner this year after Jack, and won Ducati’s first Grand Prix since Australia 2010.

Sunday’s crash was Jack’s second big off for the weekend after a highside in qualifying on Saturday saw him have to qualify on his second bike on worn tyres, which saw him well back in 20th on the grid.

Jack was disappointed with the decision not to race, but understands that with four races in a five-week period, the risk of further injury was too great.

“This isn’t the way I wanted to start the second half of the season, but that’s the way it is,” Jack said.

“It’s a shame it didn’t work out for me today but I’ll keep giving it 100 per cent and now I’m hoping to be fit to race in Brno next week, as I really like that track. I banged my foot and that’s a bit sore, as is my wrist and vertebrae with the small fractures, but hopefully I can heal quickly.”

Jack will be examined in the coming days, and hopes to be back for round 11 of the season at Brno in the Czech Republic in seven days’ time.
