FRANKFORT (AP) -- Kentucky's top horse racing doctor has resigned, a state spokesman said Friday.
Jim Carroll, the spokesman for the state agency that includes the Kentucky Horse Racing Commission, says veterinarian Lafe Nichols resigned Friday.
The chief veterinarian ensures all racing in Kentucky complies with equine medical regulations. Nichols had held the position since April 2007.
The horse racing commission regulates the conduct of horse racing and pari-mutuel wagering on horse racing in Kentucky.
Racing commission executive director Lisa Underwood said in a statement that equine medical director Mary Scollay will temporarily assume oversight of veterinary racing regulatory operations until an interim chief can be named in October. A national search will be conducted for a permanent replacement.
