Stewards for the New York State Racing Association approved Monday the use of a nasal strip for California Chrome, NBC Sports reported.
Trainer Art Sherman suggested earlier that California Chrome might forgo a chance at the Triple Crown if officials would not allow the strip at Belmont. He said it helps the colt breathe.
California Chrome will attempt to be the first horse to win the Triple Crown since Affirmed in 1978.
The 146th Belmont Stakes will take place on June 7 and will be broadcast live on NBC and streamed on NBC Sports Live Extra.
