450SX rookie Adam Cianciarulo will miss tonight’s eighth round of Monster Energy Supercross after breaking his collarbone in a qualifying incident this afternoon.

The injury brings his perfect qualifying record to an end after the Monster Energy Kawasaki rookie had been quickest across all seven rounds previously.

Cianciarulo – who was fifth in the session despite his early ending – misjudged the dragon-back, ejecting him over the handlebars and causing the clavicle injury. He will likely miss three to six weeks.

“Had a crash in Q1 and broke my left collarbone,” Cianciarulo confirmed. “Gonna have to sit this one out tonight. Sucks, but it is what it is – my fault. I’ll keep you guys updated on the recovery!”

Coming into Texas Cianciarulo currently sits fifth in the point-standings, his best results of second position coming at Anaheim 1 and San Diego. It’s unclear at this moment when he will be fit to return.
