David Ragan will take over the No. 55 Michael Waltrip Racing Toyota Camry in the NASCAR Sprint Cup Series next weekend at Kansas Speedway.
According to the team, Ragan will remain in the ride for the rest of the season, as there is no timetable on primary driver Brian Vickers' return from recurring blood clots.
After driving in the Daytona 500 for Front Row Motorsports, Ragan has run the last eight races in the Joe Gibbs Racing No. 18 car, replacing Kyle Busch, who broke a leg and a foot in the season-opening XFINITY Series race at Daytona International Speedway.
