IndyCar race director Beaux Barfield is not at the doubleheader race in Toronto because of personal reasons.

Former race director Brian Barnhart will replace Barfield in race control for Saturday and Sunday's races.

Barnhart is currently senior vice president of operations and was race director from 1997 through 2011. He was removed from race control by former IndyCar CEO Randy Bernard at the end of a controversial 2011 season in which both Will Power and Helio Castroneves had very public disagreements with Barnhart.

Barnhart will have three race stewards with him in the booth. They are Arie Luyendyk Sr., Bill Van de Sandt and Gary Barnard.

IndyCar officials gave no further information regarding Barfield's absence.
