I just read on the Thoroughbred Daily News that Blues and Royals was euthanized after suffering colitis- I am very sad to hear that since he was so electrifying in his last start, beating the tar out of the UAE Derby runners.

I very much wanted to see him run against Bellamy Road, but I guess that wasn't meant to happen.
Isn't it strange that formerly UAE-based Balletto was just retired with a colon problem and now this? The UAE runners are facing very unfortunate problems in America this year, and very close together...
What is "colitis" and is it anything like the "impacted colon" issue that Balletto faced?
