INDIANAPOLIS -- The Indy Racing League will switch its race at Kansas Speedway from July to late April next year as a buildup to the start of practice for the Indianapolis 500.

The July slot vacated by Kansas instead will be used for a road race at Watkins Glen, and a feasibility test scheduled for next week eventually could produce an IRL race at Daytona International Speedway, American stock-car racing's most famous track, league president Brian Barnhart said Tuesday.

The IRL released a partial schedule for next season with nine races. At least seven more are expected to be announced within the next two weeks.

Barnhart said the Ganassi, Andretti, Penske and Panther teams will test at Daytona Tuesday and Wednesday, to determine whether the track is suitable as a permanent IRL test site.

If that works out, he said, a race at the high-banked stock-car track would get serious consideration.

Other races already have been scheduled at St. Petersburg, Florida, the Milwaukee Mile, Texas Motor Speedway, Iowa Speedway, Nashville Superspeedway and Kentucky Speedway.

The switch in dates would put the IRL at Kansas Speedway April 29 and at Watkins Glen July 8.

Having a race the July 4 holiday week at Watkins Glen, meanwhile, would enhance the upstate New York area's attractiveness to summertime tourists, said president Craig Rust.

Barnhart said moving the Kansas race to one week before the Indianapolis Motor Speedway opens for practice would fill a seven-week gap in which the only race the past two years has been in Japan.
