Watch Now | Supercross Live! 2014 Las Vegas SX Practice

The 2014 Monster Energy Supercross Series comes to a dramatic close, with the seventeenth and final round taking place today inside Sam Boyd Stadium in Las Vegas, Nevada. With the 450 championship already decided, tonight we will see the crowning of two 250 regional titles and the annual Dave Coombs Memorial East Vs. West Shootout, which pits both region’s best against each other in a ten-lap duel for dominance.

But before any of that can happen, riders will need to get through timed qualifying, which is taking place under a scorching sun and through gusty winds. A high pressure system parked itself over the desert late in the week and moved temperatures into the high nineties, while an incoming low pressure system is bringing winds in the high teens to low twenty ranges. This factors together will make an already hard-packed and dry track even more challenging, but the sport’s best racers will have plenty of time to dial in their lines. And you can catch all of the action via this live stream, thanks to Supercross Live.

Tonight's races will be broadcast live on FOX SPORTS 1, with coverage beginning at 10:30PM EASTERN/7:30 PACIFIC. CHECK YOUR LOCAL LISTINGS FOR MORE INFORMATION...
