The 2014 Lucas Oil Pro Motocross Championship’s penultimate round brought some wild racing after morning rain turned the track to mud. On a day when Jeremy Martin wrapped up the championship in the 250 Class, Jessy Nelson and Marvin Musquin also experienced the thrill of victory. In the 450 Class, the title race between Ken Roczen and Ryan Dungey took a massive turn, with one rider gaining separation headed into the final round.
