Elliott Sadler will drive the No. 55 Toyota for Michael Waltrip Racing in five Sprint Cup events this season starting at Bristol Motor Speedway on March 18.
Sadler will drive both Bristol races, both Martinsville (Va.) races and the July 15 race at New Hampshire Motor Speedway.
Mark Martin is the primary driver of the No. 55 Toyota.
"This is an awesome opportunity," said Sadler. "We’ve been talking about this for a while, but wanted to get through Daytona before we announced it to everyone. If I had to pick a place on the circuit to start then Bristol would be my first choice. I can’t thank Michael and everyone at MWR enough for giving me this opportunity."
