Dale Earnhardt Jr. and Casey Mears have been placed on probation by NASCAR for intentionally hitting each other following the race at Phoenix International Raceway.
NASCAR has put both drivers on probation for the next six races.
Neither driver was fined or lost any points.
Contact between the two caused Earnhardt to crash with 11 laps to go in Saturday night's race.
After, Earnhardt intentionally spun Mears on the cool-down lap. Mears retaliated by bumping into the back of Earnhardt's car on pit road.
The two were teammates last year at Hendrick Motorsports, but Mears now drives for Richard Childress Racing. Both are having disappointing seasons so far. Earnhardt is 19th in the standings and Mears is 22nd.
