Doctor Says Barbaro Has ‘Some Tough Days Ahead’

Barbaro’s perilous road to recovery has suffered its biggest setback yet.

The Kentucky Derby winner faces major problems for the first time since surgery to repair the right hind leg he shattered in the Preakness Stakes seven weeks ago.

Barbaro received a new cast for a sixth time Monday, the fourth change in a week.

The latest development followed three hours of surgery Saturday night, when doctors replaced a titanium plate and many screws and treated an infection.

“I think we’re in for tough times right now. I think we’re going to have some tough days ahead,” Dr. Dean Richardson said at the University of Pennsylvania’s New Bolton Center in Kennett Square, Pa. “When a horse has a setback like this, it’s a problem.”
