LAS VEGAS (AP) Brian Vickers will run six races for Michael Waltrip Racing in the No. 55 Toyota this season, starting at Bristol Motor Speedway next week.

Vickers also will run at the August race in Bristol and both races at Martinsville and New Hampshire.

Mark Martin will drive the No. 55 in 24 races, along with the All-Star Race in Charlotte. MWR will name a driver for two road course races later this season.
