I'll Have Another galloped on Friday morning and was kind of tender, according to Doug O'Neil's brother Dennis. He was diagnosed with a swollen left front tendon and will be scratched from the race.
According to the brothers, the Preakness stakes, where I'll Have Another drove past Bodemeister in the final stretch, will likely be the horse's last race.
Dan Patrick asked Doug O'Neil on his radio show this about the horse's future and whether or not I'll Have Another was finished racing, O'Neil replied If I had to wager ... I would say yes.
I'll Have Another had a chance to be the first Triple Crown winner since Affirmed did it in 1978.
With the injury, the new favorite for Saturday's race is Dullahan, who placed third at the Derby at 5-1, followed by Union Rags who was seventh in Kentucky at 6-1, and Bob Baffert trained colt Paynter at 8-1.
