Five to remember: Texas tempers in Lone Star State

Everything is bigger in Texas, including the tempers. Here's a look back at five memorable instances of tempers running hot at the track known for no limits.

5. ON SIMMER: This didn't devolve into blows, but it underscored the feud between Joey Logano and Kevin Harvick that existed for the better part of two years. In the spring 2015 race, Harvick moved Logano up the track when his trailing No. 4 car appeared to be faster, nearly sending the No. 22 Ford into the outside wall at one of the fastest tracks on the circuit. "He blocked, and I knocked him out of the way," Harvick succinctly explained on pit road. Both in-race scanners blared with warnings to watch out for a post-race incident, though it would not come to that.

4. MID-RACE SWITCH: There was strategy behind the move, sure, but No. 48 team crew chief Chad Knaus was so frustrated with his team's slow pit stops in the 2010 fall race that he orchestrated a mid-race change. Out went his No. 48 crew over to Jeff Gordon's crew, and the No. 24 team, which had been faster that day, moved over to try and help Jimmie Johnson gain ground on Denny Hamlin, who was consistently quicker on pit road that race. Johnson would finish ninth in the race, but closed in on his fifth consecutive title later in the season.

3. GORDON VS. BURTON: An accident between these two heavyweights occurred in the same race in 2010, with Jeff Burton accepting responsibility after the sun got in his eyes. He approached Jeff Gordon to apologize, but didn't have the opportunity to do so -- that's because an angry Gordon shoved him hard and threw a swing before NASCAR officials pulled them apart ... just in time for an ambulance ride together to the infield care center.

2. PARKED: NASCAR parked Kyle Busch in 2011, taking him out of the car for the NASCAR Xfinity Series and NASCAR Cup Series events after his actions in the preceding NASCAR Gander Outdoor Truck Series race that weekend. Busch and Ron Hornaday brought out the caution after contact sent them up the track into the wall. Then, under caution, Busch drove Hornaday into the wall, igniting the full-time Truck Series driver's truck and effectively dousing his hopes at a fifth series championship.

1. THE FIGHT: Emotions boiled over, and so, too, did the tempers in 2014, the first year of the elimination playoff format. Brad Keselowski saw a hole on a late restart, and tried to dart through it. Doing so initiated contact with fellow playoff driver Jeff Gordon's No. 24, the result of which cut Gordon's tire and ruined his night. An angry Gordon approached the No. 2 after the race, and things were somewhat in control until Kevin Harvick came over and gave Keselowski a healthy nudge into the fray, sparking a fracas that left both drivers bloodied.
