Practice has wrapped up inside Houston’s NRG Stadium and some great dirt combined with a fast-yet-technical layout has set the tone for what will be a dramatic night of competition. While Ryan Villopoto sits well in control of his own destiny atop the 450SX Class standings, any mistake could have major consequences as several of his rivals can attest. The 250SX West Region is also back in action as Jason Anderson and Cole Seely prepare to resume their title fight.
FOX Sports 1 will air all the action from Houston live, beginning at 8:30 p.m. ET with Ralph Sheheen, Jeff Emig, Jeremy McGrath and Jenny Taft. Here are the storylines to watch out for when the gate drops.
