" Martin will not drive in the May 5 race at Talladega, which marks the end of the timetable for Hamlin's recovery. Sources said there is a chance Hamlin could at least start that race to collect points. If he is unable to finish he could give way to a backup driver. Because Talladega is a 2.66-mile track, a switch could be made under caution without losing a lap.
Vickers is not scheduled to drive the 55 in that race, so he is available if Hamlin can't drive or needs a backup.
JGR also looked at putting Vickers, who drives a full Nationwide Series schedule for the organization, in the No. 11 full time. But because Vickers is in line to replace Martin full time in the No. 55 next year, it was decided to give him more time with the team.
JGR Nationwide driver Elliott Sadler wasn't an option because he already is running a fourth JGR car at Kansas and Talladega with sponsors in place.
Gibbs said Hamlin, crew chief Darian Grubb and sponsor FedEx were all part of the decision process."
