Jockey Roman Chapa suffered a broken collarbone and will be off his mounts for at least six weeks after falling in a racing accident at Lone Star Park on Friday. The 35-year-old Chapa was also complaining of soreness in his calf, acccording to his agent, Shawn Bergquist, but sustained no other broken bones from the incident. "He's banged up and bruised some, and his calf hurts from where a horse stepped on it, but nothing else is broken," said Bergquist.Quincy Hamilton will replace the sidelined jockey in Saturday's Lone Star Derby (gr. III) as the rider for the Steve Asmussen-trained Rain on Monday.Chapa was thrown in Friday's seventh race at the Grand Prairie track when his mount, Substantiate, broke down near the sixteenth pole in the six-furlong event for Texas-bred claimers. The 4-year-old gelding got back up and bumped oncoming Valid Echo, ridden by Omar Rodriguez, before colliding with Gray Zephyros, ridden by Benito Morales. Both riders were unseated but escaped serious injury.The Danny Pish-trained Substantiate was vanned off the track while Chapa was transported to Methodist Hospital in Dallas, where x-rays revealed the collarbone injury."He'll let the swelling go down and heal for about two weeks, and then he'll get checked by a specialist," Bergquist said. "He has a wife and kids, so he'll go home to Houston and take a little break. He's not gonna be out long – six weeks, probably, and he may come back a little quicker if he heals well."
Chapa is fourth in the jockey standings at Lone Star, with a 17-14-19 record from 99 starts and earnings of $296,465 since the meet began April 13.
