CHARLOTTE, N.C. (AP) -- Mark Martin will drive for Joe Gibbs Racing while Denny Hamlin recovers from a fractured vertebra in his lower back.
Martin's first start in the No. 11 Toyota will be next week at Martinsville Speedway, where he wasn't scheduled to race. Brian Vickers had already been tabbed to drive Martin's car for Michael Waltrip Racing at Martinsville.
Martin has driven one other time for JGR, in the Nationwide Series last year at Las Vegas.
Hamlin is expected to miss at least five races while he heals. JGR did not specify how long Martin will be in the car, but the fifth race is at Talladega, a track Martin has opted to skip the last few years.
