CONCORD, N.C.— Michael Waltrip Racing will run only two full-time cars next season because of the loss of sponsor NAPA, part of the fallout from its attempts to manipulate a race to get Martin Truex Jr. into the Chase. Truex, crew chief Chad Johnston and 15 percent of the workforce were notified Monday they are free to negotiate with other teams. Team co-owner Rob Kauffman said the cuts were across the organization and not limited to Truex's team.
