MWR to lose another crew chief

#56 crew chief Chad Johnston has asked for his release from Michael Waltrip Racing at the end of the 2013 season. Johnston remains committed to driver Martin Truex Jr. and the #56 team and intends to battle for wins in the next seven races. But with two children and another on the way, the 33-year-old engineer turned crew chief must consider his options. Everything is uncertain, Johnston told FOX Sports on Saturday at Kansas Speedway. Obviously, were kind of in limbo right now, so everyone is minding their Ps and Qs right now and getting something lined up for next year. At the end of the day, we have to support our families and its a livelihood for us. Its a well-known fact that we need to be looking. I just want to do it the right way. Though Johnston hasnt received any concrete offers, in a perfect world he would prefer to remain with Truex and his current crew.(FoxSports)
