Dreyer & Reinbold Racing confirmed Thursday that Graham Rahal will replace the injured Mike Conway in the team's No. 24 Dad's Root Beer/Hot Wheels entry for the Iowa Corn 250 at Iowa Speedway on June 20.

"We are thrilled to have Graham drive for us this weekend. We obviously wish that Mike could be with us, but we just want him to have a quick recovery. Iowa will be big weekend for DRR as we unveil the Dad's Root Beer one-off paint scheme designed by Hot Wheels on Father's Day. Graham was a perfect fit and we couldn't be happier to have him behind the wheel," said Dreyer & Reinbold Racing co-owner Robbie Buhl.

D&R will be Rahal's third different IndyCar team this season since his split with Newman/Haas at the end of 2009. Rahal, who drove for Sarah Fisher Racing at St. Petersburg, Barber Motorsports Park and Long Beach, and his father Bobby's team at Indianapolis – while also being linked with a possible return to Newman/Haas, which did not come about – will take over the seat occupied at Texas last weekend by Tomas Scheckter. Rahal's arrangement is also a one-race deal for now.

"Dreyer & Reinbold Racing has clearly done an impressive job this season and I really have to thank Robbie, Dennis, the team, and Dad's Root Beer for this opportunity to compete in Iowa," said Rahal. "I also want to wish Mike Conway a quick recovery and hopefully we can bring home a good result for him."
