I’ll Have Another was scratched from Saturday’s Belmont Stakes, trainer Doug O’Neill said Friday on The Dan Patrick Show.
O’Neill said the Kentucky Derby and Preakness Stakes winner had tendinitis in a front leg.
O’Neill said he’d likely rest I’ll Have Another for three months, and there was a chance the 3-year-old will never race again.
I'll Have Another was scheduled to break from the No. 11 post Saturday in his bid to complete the Triple Crown.
The Kentucky Derby and Preakness winner was made the 4-5 morning-line favorite for Saturday's race.
Eleven horses were entered Wednesday to take on I'll Have Another in his bid to win the Triple Crown for the first time since Affirmed swept the Derby, Preakness and Belmont in 1978. Only 11 horses have accomplished the feat, while 19 have been tripped up in the Belmont after winning the first two legs.
