Big Brown's

trainer appears to be a late scratch for today's House hearing on the safety of thoroughbred racing, removing the most anticipated witness from Congress' latest look at sports and steroids.

Rick Dutrow

said he has had a virus for several days and did not feel well enough to travel, the Associated Press reported.

"I'm sorry he's not here," said Rep.

Ed Whitfield

of Kentucky, the subcommittee's ranking Republican. "We had a lot of questions for him."

The Subcommittee on Commerce, Trade, and Consumer Protection had been looking forward to hearing from the trainer known for his candor and for methods that were brought into question after his star horse's stunning last-place finish in this month's Belmont Stakes.

Dutrow said that he used a legal steroid on Big Brown, and that the last dose was given in April. The colt ran the race with a crack in his left front hoof in a failed attempt to become the first Triple Crown winner in 30 years.

An AP survey last week found that thoroughbred racetracks reported more than three horse deaths a day nationwide in 2007 and 5,000 since 2003. The impetus for the hearing came when
