Trainer Nick Zito reported Wednesday morning that The Cliff's Edge had some "pulsation" in his right front foot, making the Gulch colt questionable for Saturday's Preakness Stakes (gr. I).Zito said he will enter the colt owned by Robert LaPenta in the Preakness and decide Thursday afternoon whether he will scratch out of the race.The trainer said later that the problem was likely a bruise that was being treated with warm water and Epson salt and ultrasound therapy. "He could be 100% tomorrow," Zito said, noting the reason for going ahead and entering in the the Preakness.The fifth-place finisher in the Kentucky Derby (gr. I) had been scheduled to go to the track at Pimlico to be jogged at 6:15 (ET) Wednesday. Instead of going immediately to the track, the colt walked inside the shedrow for about 20 minutes before walking under the shedrow for about an hour after the tack was put on him. The colt then jogged a couple of times before going to the track.Zito said everything looked OK while the colt was jogging on the track and when he left the track, but that he was going to call in Dr. Dan Dreyfus to examine The Cliff's Edge.Following the Derby, Zito reported that The Cliff's Edge had lost both front shoes during the race over a sloppy track at Churchill Downs. Zito said the shoes were replaced last Wednesday. Zito is also expected to enter Sir Shackleton in the Preakness.
