IndyCar cancels season-ending banquet following death of driver Wheldon at Las Vegas

LAS VEGAS, Nev. - IndyCar has cancelled its season-ending banquet following the death of two-time Indianapolis 500 winner Dan Wheldon at its season-ending race.

Wheldon, the 2005 IndyCar series champion, was killed Sunday when his car got caught up in a 15-car wreck, sailed over another vehicle and struck a catch fence 11 laps into the race at Las Vegas Motor Speedway.

IndyCar had planned to hold a celebration for the 2011 season Monday night at Mandalay Bay Resort on the Las Vegas Strip.

One of the series' most popular drivers, Wheldon was 33 when he died, leaving behind a wife and two small children.

IndyCar said information on a public memorial for Wheldon will be released at a later date.
