Australia’s Chad Reed has been fined $5000 ($6500 AUD) and docked five championship points after his controversial run-in with defending Monster Energy AMA Supercross champion Ryan Dungey in St. Louis.

Reed was going a lap down in 16th during the main event when caught by title-rivals Eli Tomac and Ryan Dungey, however he appeared to make it difficult for the latter to pass as Tomac sprinted away to victory.

Despite blue flags being waved, it took multiple laps for Red Bull KTM’s Dungey to make his way by Reed (Monster Energy/Yamalube/Chaparral/Yamaha Financial Services/Yamaha), and by then Monster Energy Kawasaki’s Tomac extended his lead to a commanding seven-second margin.

It was determined by the race director that Reed ‘failed to follow the direction of the AMA officials indicated by the blue flag. In doing so, rider 22 did impede the faster rider’s progress’ and as a result, was fined and docked the five championship points he earned in St. Louis.

The $5000 will be donated to the Alpinestar Mobile Medical Unit, however for Dungey, he’s expressed his frustrations over the incident that has lit-up social media this week.

“I just don’t know why he has to get involved with me and Eli’s position,” Dungey said after the race. “If he was on the same lap, I’d understand, I think we all would, but he’s a lapper. I guess I don’t know where this attitude and everything is coming from.

“That guy’s been around a long time and that much experience, you’d think he would understand what it’s like to be in the position that I am, but he has no respect for us and what we’re doing, what we’re trying to do. I have a lot of respect for the guy, still do, but tonight was a low-blow.”

Dungey’s lead over Tomac now sits at just four points as the series heads to CenturyLink Field in Seattle. Reed, who has not made a statement since the incident, is ninth in points.
