Busch had to pit for fuel with 11 laps remaining after leading 302 of the scheduled 400-lap race. Keselowski went the final 89 laps without stopping for gas.
Team owner Joe Gibbs said in Thursday's statement the organization appreciates its relationship with Toyota, and that Busch shouldn't have cursed at the manufacturer.
"Kyle recognizes that his comments and the tone of his comments were misguided. We've been able to work through this issue and I think everyone is ready to get back to the focus being on racing and Talladega," Gibbs said.
