Rockstar Energy Husqvarna Factory Racing’s Colton Haaker will be forced to sit out the final three rounds of the AMA EnduroCross Championship and will thus relinquish his fight to successfully defend his title in the US.

Enjoying a solid season of competition in the US, Haaker won the opening round of the 2017 AMA EnduroCross series in Las Vegas and then went on to claim top three results in the following three rounds of the series.

Due to an injury sustained at the beginning of the EnduroCross season, Haaker has already undergone minor surgery to remove the Bursa Sac in his elbow and clean up the remainder of an existing staph infection.

While doctors are currently unsure of the recovery time needed, the Rockstar Energy Husqvarna Factory Racing rider is already looking to be back in time to defend his FIM SuperEnduro World Championship title. The 2018 SuperEnduro series kicks off in Poland on December 9, 2017.
