Jockey Austin Lovelace will be riding in a race for the first time in more than six years Sunday at Louisiana Downs, but he has not been too far removed from the track. At least geographically. Lovelace had been working at an automotive company in Shreveport, La., until this past spring, when the plant closed. He then returned to his racing roots, began galloping horses, and on Sunday has been named to ride Dark Tunnel in the third race for trainer Charlie Hukill. It will be Lovelace’s first mount since May 20, 2004.
