LOUDON, N.H. — The reverberations continue following the attempted race manipulations by the Michael Waltrip Racing team at Richmond International Speedway Sept. 7.
NAPA Auto Parts, primary sponsor of MWR driver Martin Truex Jr., announced Thursday it was going to withdraw its multimillion-dollar sponsorship of MWR at the end of the season, sending shock waves through the racing community. The embattled Michael Waltrip will lose not just the sponsorship, which was in the first of a three-year run and estimated to be worth $16 million, but also the Chase bonuses for drivers and the racing team. If Waltrip doesn’t find Truex a new primary sponsor, he could lose his driver as well. Full story for BostonGlobe.com subscribers.
