At the Subway Fresh Fit 500 at Phoenix International Raceway, after a pit gamble didn’t pay off, Dale Earnhardt Jr was dropping back in the field. Casey Mears got into him, and Jr spun and hit the wall. Jr sustained damage, but was able to continue. He finished 31st.
On the cool down lap, Jr spun Mears, showing him his displeasure. As Jr headed to the garage, Mears caught up with him and bumped him several times.
