NPS Monster Energy Kawasaki’s Dylan Long will skip the second half of the 2015 Australian Supercross Championship after crashing out with a concussion at the Adelaide, South Australia, round at the end of last month.

The 21-year-old starred in his guest role at Kawasaki during the second half of the MX Nationals, but eighth at Jimbooma was his lone finish in the first three rounds of supercross.

“Due to the crash I had at Wayville I will not be racing the rest of the supercross this year,” Long announced on social media. “It sucks, but I’m not 100 percent yet and there’s no point racing supercross when you’re not 100 percent – can only end up in more injury!

“Unfortunately that means I don’t get to ride underneath the Kawasaki Australia MX Racing Team truck again, but can’t thank Troy Carroll, Michael Marty and the rest of the team enough for all their help and the awesome opportunity!

“Now onto a new stage for next year. Thanks to everyone who supported me this year it’s amazing to have people like you behind me but will be back next year fitter and stronger!”

With NPS Monster Energy Kawasaki already signing Matt Moss to the roster for 2016, Long has been linked alongside Jay Wilson in a new-look factory Honda operation to be introduced next season.
