I'll Have Another will miss the 2012 Belmont Stakes due to an undisclosed issue, which will likely be explained during a 1 p.m. press conference.

The resounding response on Twitter is disappointment that the horse won't get an opportunity to become the first Triple Crown winner since Affirmed in 1978, but respect for the horse's corner for considering safety first.

A small sampling follows of tweets mentioning the horse's handle, @Ill_HaveAnother.

Heartbroken for @Ill_HaveAnother and everyone on his team. Props to the team though for putting safety first. #TripleCrown

Hey people...just be thankful @Ill_HaveAnother didn't break down in the race...he gets to make babies & is safe from anything terrible.

So sorry that @Ill_HaveAnother is not able to race on Saturday! He's an amazing horse and will always be in our hearts!
