David Ragan reportedly being signed by Michael Waltrip

Michael Waltrip Racing is planning to sign David Ragan to drive the team's #55 Toyota in the Sprint Cup Series for at least most of the rest of the 2015 season, according to reports on Friday. Ragan started the season at Front Row Motorsports in the #34 Ford, but has been substituting for the injured Kyle Busch at Joe Gibbs Racing in the #18 Toyota since the second race of the season at Atlanta. Brian Vickers, the regular driver of the #55, drove at Las Vegas and Phoenix last month before once again being sidelined by his blood clots. Development driver Brett Moffitt has been in the car since then. He, Joe Nemechek and Chris Buescher have also driven the #34 in Ragan's absence.
