Triple Australian motocross champion Dean Ferris is feared to have suffered a knee injury in his return to the MXGP World Championship at Matterley Basin in Great Britain yesterday.

Ferris, who’s currently filling in for injured athlete Romain Febvre at Monster Energy Yamaha Factory Racing in a three-race deal, completed moto one in 15th position, however a crash at the beginning of race two called for a premature end to his weekend.

He’ll undergo further medical examination to determine the extent of the injury, and ultimately come to a conclusion on if he can continue racing this season.

“It was a tough weekend, but I got more comfortable in every session,” Ferris explained. “I thought the last fifteen minutes of the race I found my groove and had some really good lap-times, so I was content with that. In moto two, I went down on the start and I have hurt my knee, so that will need to be assessed.”

The injury could jeopardise Ferris’ intentions to lock-in a deal in the Lucas Oil AMA Pro Motocross Championship, which was his plan after earning the Pirelli MX Nationals MX1 crown for three consecutive years with CDR Yamaha Monster Energy.
