Dale White, Team Manager/Entrant: "We are following our team's policy and have released Tomas from his contract with Petersen Motorsports/White Lightning Racing effective immediately. While this is extremely regrettable to Mike Petersen, myself and the team, Tomas has been on probation with the team, as well as with IMSA, since Lime Rock Park and our policy and understanding with Tomas is clear. It was understood that we would not and could not tolerate any further penalties and that any additional penalty would be dealt with in this manner. Regardless of the circumstances surrounding the actual incidents, it is our practice to follow the determination of the stewards."
