David Ragan to move to MWR to replace Brian Vickers in No. 55 for rest of the season

David Ragan will move to Michael Waltrip Racing next week and finish the season as the replacement driver for Brian Vickers.

Ragan has been filling in at Joe Gibbs Racing for Kyle Busch since the second week of the season. Busch is expected to return soon, and JGR has wanted to give 18-year-old development driver Erik Jones some seat time in a Sprint Cup car.

That frees up Ragan, who will take over the No. 55 Toyota at Kansas Speedway. Team co-owner Michael Waltrip will drive the car Sunday at Talladega.

Vickers missed the first two races of the season as he recovered from heart surgery. He returned for two races but was sidelined again in March with recurring blood clots.

No timetable has been set for Vickers' return.
