AJ Allmendinger will drive the No. 51 Phoenix Racing Sprint Cup car Sunday at Martinsville Speedway. Allmendinger, who was suspended earlier this season for violating NASCAR's substance abuse policy, has driven the past two races at Charlotte and Kansas, where he finished 24th and 35th, respectively. Phoenix Racing general manager Steve Barkdoll said the decision to go with Allmendinger was based on how he has performed over the past two weeks.
