9. Logano and Hamlin on track fight in Nascar racing: An on-track run-in caused some heated pushing and shoving between Logano and Hamlin at Bristol in March 2013, the two drivers exchanged blows at Fontana. Its after effect was that a collision occurred on the second-to-last turn of the race with both drivers jockeying for the win, and it resulted in Hamlin hitting the wall head-on and taking a trip to the hospital.
