DAYTONA BEACH, Fla. (AP) -- A.J. Foyt has been hospitalized in Houston for complications from knee surgery and will skip the 50th
anniversary of the Rolex 24 at Daytona.

The 77-year-old Foyt had knee surgery two weeks ago, and an
infection sent him to the hospital Wednesday. A spokeswoman for the four-time Indianapolis 500 winner said Friday that Foyt may stay in the hospital through the weekend.

She said he had been up and walking since the surgery but developed an infection this week. Foyt is the only driver to win the Indianapolis 500, the Daytona 500, the 24 Hours of Daytona and the 24 Hours of Le Mans.

Foyt was scheduled to be the grand marshal Saturday at Daytona
International Speedway.
