Roger Penske has fired team president Tim Cindric, IndyCar managing director Ron Ruzewski and IndyCar general manager Kyle Moyer in the wake of an Indianapolis 500 cheating scandal.

The firings and Penske’s statement have been his first public reaction since two-time Indianapolis 500 winner Josef Newgarden and teammate Will Power were found to have an illegally modified spec part on their cars ahead of last Sunday’s final round of qualifications for the Indy 500.

Team Penske drivers and executives were penalized ahead of the Indianapolis 500 for the second consecutive year.
