LOUISVILLE, Ky. – Chamberlain Bridge, one of the favorites for the $1 million Breeders’ Cup Turf Sprint, popped an abscess in his right front hoof Friday and had to miss a scheduled workout this weekend, although trainer Bret Calhoun is still optimistic the millionaire gelding can make the race Saturday. “It’s still a little hot, pulsey, sore,” said Calhoun. “We took the shoe off him after we found it, soaked it, and packed it several times through the day. We’ll be doing some more of the same today. It actually looks pretty good. I’m hopeful we can put the shoe back on him [Sunday] and maybe even take him to the track.” Calhoun said the missed workout “is no big deal, really. I’ve got him where I want him anyway. He doesn’t need anything. I’ll just train him up to the race and hope to get him in the gate Saturday.” Chamberlain Bridge, a 6-year-old gelding, has won 15 of 30 career starts and earned $1,045,245. Jamie Theriot would have the mount. The five-furlong Turf Sprint drew 18 pre-entries.
