Per tonight’s broadcast of the SuperMotocross World Championship Final in Las Vegas, Haiden Deegan has suffered a broken left collarbone.

In the final 250SMX moto of the season, Deegan attempted a block pass on race and championship leader Jo Shimoda, which he hoped would result in a points swing his way for the title. However, as both Shimoda and Deegan went down, only Shimoda remounted. Deegan went to pick up his bike but could not and immediately began pointing towards his left arm/shoulder. He walked off and started talking to the Alpinestars medical crew before getting help taking his helmet off.

Now, it was confirmed on the TV broadcast that Deegan has suffered a broken collarbone in the incident. He officially scored fourth in the 250SMX championship after winning both 250SMX titles in the first two seasons of the format.

About an hour later, Chase Sexton went down late in the final 450SMX moto. Not only is that three straight years with Sexton suffering a DNF at the SMX finale, but that is two big crashes for two members of Team USA for the upcoming Monster Energy FIM Motocross of Nations the first weekend in October. While we have no word on Sexton’s condition at the moment, this was a tough night for Team USA. What happens now?
