The Dutchman, who has taken two out of the last six moto wins on his RM-Z250, lost control of his machine cresting a jump, landed awkwardly, and ripped the exterior lateral ligament on his left knee, as well as sustaining a compression-fracture.
Coldenhoff will miss the majority of the season, hoping to return for the final two meetings of the year.
He said, “I am so disappointed. I scrubbed a jump and must have just caught my wheel because it set me a little short; I almost saved it. There was a lot of pain initially and we went straight for a check but the x-ray didn’t reveal much damage due to the swelling. It is only when we saw the MRI that we got the bad news.”
“I had maximum points in the Dutch championship and was third in the World with Valkenswaard next. It would have been a good season, but now I have to focus on coming back from this.”
