Please don't drink to this 50th anniversary

This would be more exciting news were it not for legal circumstances.

Al Unser Jr. will tote six Indianapolis 500 driving victories and a lot more history when the No. 50 A.J. Foyt Racing entry makes its qualifications attempt for the 91st Indianapolis 500.

Unser, a two-time winner of "The Greatest Spectacle in Racing," is joining forces with A.J. Foyt Racing and its full-time IndyCar Series driver, Darren Manning, for the Month of May. Their Honda-powered Dallaras will take the track for the first time May 8. The run for the AAMCO Transmissions Pole Award is May 12.

The No. 50 car is in recognition of Foyt's 50th anniversary in Indy car racing. The 91st Indianapolis 500, scheduled for Sunday, May 27, will be Foyt's 50th in a row as a participant. He won in 1961, 1964, 1967 and 1977 as a driver and in 1999 as a team owner.

Unser will be the 50th driver – and second Unser -- to run for Foyt since he began owning race cars in 1965. (MORE)

"There's a chance it might get resolved before that date," Unser's lawyer, Andrew Leavitt, said following the brief court hearing. Leavitt declined to address circumstances surrounding Unser's Jan. 25 arrest. (MORE)
