William Byron had a chance to win Sunday's NASCAR Cup race at Las Vegas Motor Speedway, but lost the lead after nearly losing control in Turns 1 and 2. As he refocused and set his sights on taking the lead back, Byron's race ended abruptly in a violent and unnecessary wreck.
Byron's No. 24 Hendrick Motorsports Chevrolet slammed into the back of the slowing No. 10 Kaulig Racing Chevrolet of Ty Dillon, who was off the lead lap and attempting to pit. What exactly happened to cause the bizarre pit entry smash-up?
