Self did not state what led to the failed drug test.
Self said the drug test took place earlier this season at Daytona. He finished ninth at Daytona (Feb. 15) and was 27th at Atlanta (Feb. 23) and 15th at Las Vegas (March 1). AM Racing announced before the Martinsville race (March 23) that Self was being replaced by Bubba Wallace, who also drove for the team at Texas last weekend.
Here is what Self wrote on social media:
“To each of my fans, team partners, crew members, and fellow NASCAR members, I ask for your grace and understanding in this difficult season of adversity, and ask that you would accept my apology for what has happened. It is an honor to be involved in a premier sport so great as ours, and I am truly crushed for what has happened.
“It has been incredibly disheartening since learning of the results from the random drug test taken earlier this season at Daytona, through our sanctioning body, and for the news announced (Monday).
“The news and positive results have caught me as a surprise. Being a driver, I am expected to be a steward for our sport – someone who pays attention to even the most minute of details, just as our race team does with our trucks in competition. Moving forward I promise to those who will follow this journey, that I will aim to the utmost of my ability to do a better job at paying close attention to what I consume, and allow into my body, as an athlete.
“I will work closely with NASCAR through this process to learn more about what has happened, and to ensure that I am able to return to competition as quickly as possible.
“Moving forward, I would be grateful to have your prayers as I prepare for the days ahead. I take comfort in knowing that God has a plan for the through this, and that as 2 Corinthians 12:9-10 explains, will come through this stronger ready to tackle what lies ahead. Thank you for your support and understanding.”
Shortly after Self’s suspension was announced Monday, the team said it was working on finding a replacement in Self’s absence. The next Truck Series race is May 3 at Dover International Speedway.
