Rockstar Energy Husqvarna Factory Racing’s Zach Osborne is out for the remainder of the 2018 Pro Motocross season.

The disappointing news comes after Osborne was involved in a first turn pile-up during the start of Moto Two at the Thunder Valley National  last weekend in Lakewood, Colorado.

During the pile-up, Osborne sustained a shoulder injury, a torn labrum, which will require surgery to get the Husqvarna rider back to riding fitness. His doctors expect the recovery time needed extends past the current 2018 motocross season, hence his withdrawal from racing.

“I am extremely bummed to say the least, Osborne said. This fourth consecutive championship aboard the FC 250 was one that I wanted bad. It’s almost surreal that it has come to an end, but I know everything happens for a reason. I’ll use this time to prepare mentally and physically for the challenge of my first year in the 450 class. I am excited to get my recovery started and move onto the next step of my career!”

Husqvarna Factory Racing expect Osborne to make a successful recovery, however in the midst of having two injured 450 riders, Rockstar Energy Husqvarna Factory racing have announced that the one and only Phil Nicoletti will be filling in aboard the FC 450 Rockstar Edition, for the remainder of the Pro Motocross season. Nicoletti comes to the team with thirty top-ten finishes in his Pro Motocross racing career.

“I am happy to have the opportunity to finish out the Pro Motocross season with the Rockstar Energy Husqvarna Factory Racing team, he said. I look forward to getting on the bike and showing everyone what I have. Thank you to everyone backing me, see you at the High Point National!”
