LOUISVILLE, Ky. -- A total of 22 horses have been entered for Saturday's Kentucky Derby, two more than the maximum allowed field.
The entry box closed on Wednesday, when the draw to determine post positions will also be set. The field is limited to the top 20 horses based on earnings in graded stakes races.
Leading the way is Uncle Mo, who is being treated for a gastrointestinal infection. Owner Mike Repole has said if the colt isn't sufficiently recovered, then he won't run in the 1 1/4-mile (2,000-meter) Derby.
Uncle Mo galloped on Wednesday and later stood in the starting gate to familiarize himself with the surroundings.
Other entries for the 137th Derby are Florida Derby winner Dialed In, Arkansas Derby winner Archarcharch and Comma to the Top, runner-up in the Santa Anita Derby
Other horses entered are Louisiana Derby winner Pants on Fire, Santa Anita Derby winner Midnight Interlude, Soldat, Brilliant Speed, Irish import Master of Hounds, Twice the Appeal, Nehro and Mucho Macho Man.
The rest of the entries are Decisive Moment, Animal Kingdom, Stay Thirsty, Santiva, Watch Me Go, Shackleford, Twinspired, Derby Kitten, Sway Away and Ruler on Ice.
