During the racing week spanning Nov. 15-19 Chuchill moved all its grass races to dirt and has not run a grass race since the River City Stakes on Nov. 11. Churchill, however, has continued carding grass races, and Darren Rogers, senior director of media at Churchill, said in an email on Sunday that the status of the turf course remains “day to day” for the final week of the race meeting. Jockeys expressed concern over the course’s safety earlier this month.
