Migliore escaped with only minor injuries and may be able to return to riding on Wednesday's card.
Migliore complained of pain in his right arm and the ribs on his left side after falling from Iron Deputy near the three-sixteenths pole and was taken to the hospital by ambulance. X-rays showed he did not have any fractures.
During a visit to the jockey's room Monday morning, Migliore said he might resume riding this week.
"It's a day-to-day thing," he said. "The arm is still swollen, but it went down a whole lot after I kept it in ice all night long at the hospital.
"It looks way better than it did yesterday, and if it improves that much tomorrow, I might even be able to ride on Wednesday. We'll see how it goes."
Migliore took off each of his six mounts on Monday, and Saratoga is dark on Tuesdays. One of his cancelled calls came aboard American Style in the featured grade II National Museum of Racing and Hall of Fame stakes. Ironically, Castellano picked up the mount.
Castellano, aboard the Nick Zito-trained Quest in the Jim Dandy, made contact with Iron Deputy from the outside. Iron Deputy stumbled, dropping Migliore. Quest finished second but was disqualified and placed
Following the race, Castellano said he tried hard to keep Quest from lugging in. Castellano said he didn't see Migliore and thought he was clear when he came over.
Migliore had a different take on the incident.
"It wasn't like I just ran up in there," Migliore said. "I had my position for about a quarter of a mile.Castellano squeezed me, and down I went."
The arm was the same one Migliore broke in a spill at Belmont Park in July 1999 which kept him out of action for more than five months. He has carried two plates and 16 screws ever since.
