We have seen it a number of times already this year: drivers showing emotion after the pre-season “Boys, Have At It” edict from NASCAR. To name a few: Joey Logano vs. Kevin Harvick, Jeff Burton vs. Kyle Busch; Logano vs. Ryan Newman; Todd Bodine vs. Kyle Busch.

But this past weekend might have been the most interesting case in point.

During a late-race caution at Texas, Jeff Burton and Jeff Gordon wrecked on the backstretch. Gordon, clearly upset, got out of his car, walked to Burton and, well, threw down.

The shoving match between NASCAR’s two elder statesmen was quickly broken up, but the bad feelings may continue. Here’s what Gordon had to say after the incident: “I’ve always had a tremendous amount of respect for him, but I certainly lost a lot of respect today.”
