Al Unser Jr. will race again at Indianapolis Motor Speedway during a Sportscar Vintage Racing Association event in June.
The two-time Indianapolis 500 winner will compete in the "Indy Legends Pro-Am." The June 8 feature on Indy's road course is for veterans of the Indianapolis 500 and already has an announced field that includes Lyn St. James, Willy T. Ribbs and Mark Dismore.
The 40-minute race of American muscle cars will include 1967 to 1972 vintage Corvettes, Camaros and Mustangs. The Indianapolis 500 veterans will be paired with amateur drivers, each taking a 20-minute stint. Five minutes will be allotted for driver change.
Unser Jr. is a two-time IndyCar champion. He has 34 career victories and won the Indy 500 in 1992 and 1994.
