The Associated Press has learned that Michael Waltrip Racing will run only two full-time cars next season because of the loss of sponsor NAPA.

Team owners Michael Waltrip and Rob Kauffman on Monday began telling employees of their decision. Those affected were told they are free to begin looking for a new job immediately.

Two employees spoke to the AP on condition of anonymity because MWR had not publicly announced its decision.

The car that Martin Truex Jr. currently drives will run a partial schedule in 2014.

NAPA decided to leave MWR at the end of the year — fallout from the team's attempt to manipulate the finish at Richmond to get Truex into the Chase for the Sprint Cup championship.
