, who is known to many in the NASCAR community as 'Rowdy Busch', was racing rookie Joey Coulter
for the 5th position in Saturday's Camping World Truck Series Race on the final lap. Coulter passed Busch, and squeezed him up next to the wall, forcing Busch to retreat and finish 6th.
After the race, during the cool-down lap, Busch got up next to Coulter and gave his car a bump. This apparently angered Coulter's team owner, Richard Childress
, as he took it upon himself to confront Busch about the incident 30 minutes later in the garage area.
According to several eye-witnesses, Childress found Busch, handed his watch off to his grandson Austin Dillon, who drives the #3 Cheverolet in the series in a truck also owned by Childress, and walked directly up to Busch.
Within a short amount of time, Childress reportedly had Busch in a headlock, and had thrown several punches. Busch quickly got into a defensive position on the ground, and when he came back up, Childress threw another punch before the two were seperated.
NASCAR officials say they are investigating
This is hardly the first time Busch has had trouble with a fellow racer. He has had incidents with at least a dozen fellow compeitors in the past several years since he broke in to NASCAR at the age of 18 in 2005.
Just weeks ago Busch got into an altercation
with Kevin Harvick, who also drives for Childress. Following the race, Harvick got out and attempted to confront Busch, who was still in his car. Busch drove off, bumping into Harvick's car and sending it into a wall without the driver.
Busch holds the record for most wins in the Trucks series, and is 1 win away from tying 51-year-old Mark Martin for the most wins in the Nationwide Series.
