UPDATE: hearing that DEI has decided not to field a 5th team for Regan Smith at Watkins Glen and the #81 will be or has been withdrawn.(8-6-2008)


UPDATE2: DEI has withdrawn the entry of its #81 Sprint Cup car for Regan Smith for Watkins Glen this weekend after NASCAR informed the team that it couldnt put Smith in that car because of the four-team limit. Teams are permitted to enter a fifth car for a maximum of seven races for a rookie to get the driver familiar with Sprint Cup competition. Smith, an upstate New York native, has 20 starts this year, and NASCAR determined he did not fit the criteria for the fifth-car exception, NASCAR spokesman Kerry Tharp said Wednesday. DEI would have been allowed to put Aric Almirola in that car because Almirola has five starts this year, Tharp said. Almirola, who will take over driving the #8 car next season, already was entered in the #8 car for The Glen in place of veteran Mark Martin, who is driving the majority of the Cup races this year while Almirola fills in the rest. We brought it to their attention that [Smith] would not be permitted to run in the fifth car, Tharp said. We told them they could move Aric Almirola into that fifth entry. They went back to discuss it and decided not to enter the fifth car.(SceneDaily)(8-7-2008)
