Horse trainer Todd Pletcher has been suspended for 10 days and fined $1,000 stemming from a positive drug test taken on Forte, the morningline favorite of the Kentucky Derby who was scratched with an injury just hours before the race.

Forte crossed the finish line first at the Hopeful Stakes in Saratoga on Sept. 5 but was disqualified after testing positive for meloxicam.

Forte's owners, Mike Repole and Vincent Viola, will also forfeit their $165,000 in winnings.

Pletcher has appealed the suspension, thus allowing him to work leading up to the May 20 Preakness Stakes.

Forte was scratched from the Derby with a foot injury, and he will not race next Saturday in Baltimore. His injury, though, was far from the biggest controversy at the racetrack that week.
