Promoters are at work trying to arrange a Jermain Taylor prize fight for the Summit Arena in Hot Springs on Arkansas Derby day, April 14. That could create some additional buzz for an event tht always attracts 60,000 or so. The fight crowd could also keep the Oaklawn Park casino hopping after the horse racing is over. Taylor, the 33-year-old former middleweight champ, is on the comeback trail.
