Dan Kneen suffered two cracked vertebrae after coming off his bike during racing at Jurby yesterday (Sunday).
According to his mechanic 'Slick' Bass, Dan did a massive highside and slid down the track, rather than onto the grass.
He's definitely out of BSB opening round at Brands Hatch this weekend and there will also be question marks about his ability to compete at the North West 200 and the TT.
