John Hunter Nemechek scored his second victory of the season during the Chevrolet Silverado 250 at the Canadian Tire Motorsport Park in Ontario, Canada. However, the winning move caused quite the commotion among fans and drivers alike.

Nemechek, who was already locked into the Chase with his Atlanta win, bumped Cole Custer in the final corner, slammed into the driver’s door and eventually into the grass before crossing the finish line inches ahead of Custer.

"I caught the double-zero there and we didn't wreck him for the win,” Nemechek said “Rubbin's racing, but if I would've been in the same spot, he would've done the same thing to me to get a win. You have to do everything you can to get a win here, but I can't thank all my guys enough. They worked their butts off."

Nemechek celebrated with a burnout before officially being announced the winner and exited his truck to receive the checkered flag. Custer, who is in a must-win situation to lock himself into the Chase, tackled the NEMCO Motorsports driver to the ground before officials intervened.

"I got taken out," Custer said of the incident. “He hit me going into the second-to-last race corner and he hit me again."

The JR Motorsports driver, who led a race-high of 39 laps, was obviously frustrated about the situation that led to another missed opportunity to secure his place in the Chase. Custer has one last chance next weekend at Chicagoland Speedway to earm a shot at running for the 2016 Camping World Truck Series title.

"I was expecting it, kinda, because he’s raced a lot of people like that but it’s just a shame because it was a great chance to get into the Chase and he took it away from us," Custer stated.

Nemechek, who led 19 laps in the event, won by a margin of 0.034 seconds.

A Look Forward to the Chase

Only one race remains before the start of the Chase for the first time in the series, and several drivers are heading into Chicagoland fighting for the last remaining available position.

Tyler Reddick quietly recovered to finish sixth after a spin. He sits 11th in points, 14 points below the cutoff.

Cameron Hayley remains consistent with a 9th place finish as he sits 10th in the standings. A win can lock him into the Chase and secure his chance at running for the championship.

Or perhaps someone else will stake their claim and pull off a last chance victory quite literally. After all, it is "Win and you're in."
