McKinlay made news last year when he treated Kentucky Derby and Preakness winner Big Brown for the same ailment.
Considered one of the favorites for the Run for the Roses, Quality Road developed a crack on his right-hind quarter during his track record-setting victory over Dunkirk in the Florida Derby (G1) at Gulfstream Park on March 28.
"It's ice cold," McKinlay said. "He's moving well and he's ready to go."
T.A.H. sources close to the horse said earlier this week that the hoof was "cool and tight" and showing new growth from the coronet band. You horse guys/gals will understand that stuff...
Trainer Jimmy Jerkens is planning on heading to Louisville, Kentucky, on Tuesday, and may fit one more breeze into the bay colt before he ships.
If you want to go all veterinarian/blacksmith here's a video of a quarter crack repair...not QR's, but all of them are similar. http://www.youtube.com/watch?v=nLqOOtfOL84
