The 2012 AMA Supercross Championship headed to Dodger Stadium in Los Angeles Saturday evening for Round 3 of 17, a race plagued by a red flag on the very first lap in the SX class.

During the start of the Supercross main event, last week's winner at Phoenix, Red Bull KTM's Ryan Dungey took the holeshot, and was quickly engaged in a fierce battle with the reigning Supercross champion, Monster Energy Kawasaki's Ryan Villopoto.

But the race was red flagged when Star Valli Yamaha's Ryan Morais landed on Muscle Milk Honda's Trey Canard. The scary incident had medical staff attending to the downed Canard before he was taken off track. According to various Tweet reports, Canard fractured his back and undergo surgery, and Morais broke his jaw; no further reports were released as of this writing.

On the restart, Monster Energy Kawasaki's Jake Weimer got the holeshot ahead of Two-Two Motorsports Chad Reed, JGRMX Yamaha's James Stewart and Dungey. By the sixth lap, Reed moved into first, holding the position to take his first win of 2012 AMA Supercross.

A three-way battle begin between Weimer, Stewart and Dungey, but Weimer crashed, falling back, and so did Stewart. Due to the crashes, Dungey moved into second, where he eventually finished. Stewart would take third.

The man who won the season opener, Villopoto, took a hard-earned fourth following a start from the back of the pack after mowing over a tuff block. Fifth would go to Rockstar Maktia Suzuki's Brett Metcalfe.
