Brett Moffitt to run No. 55 at Martinsville

Brett Moffitt will drive the Michael Waltrip Racing No. 55 Toyota in place of Brian Vickers, who will miss the next three months of competition after doctors discovered a recurrence of blood clots last week. Vickers has resumed taking blood-thinning medication, which precludes him from racing.
 
Moffitt, a developmental driver for MWR, is scheduled to make his 12th Sprint Cup start and his first in the premier series at Martinsville in Sunday's STP 500. He finished 22nd Sunday at Auto Club Speedway.
 
Chris Buescher, a NASCAR XFINITY Series regular, will return to the Front Row Motorsports No. 34 Ford for the second straight week. Buescher finished 20th in his Sprint Cup debut Sunday at Auto Club as a last-minute fill-in when Moffitt was named as Vickers' replacement.

Front Row later confirmed Buescher's return to the No. 34 on Twitter.

 
Buescher ranks second in XFINITY Series standings, just five points behind series leader Ty Dillon.
 
David Ragan will continue as interim driver of Joe Gibbs Racing's No. 18 Toyota in place of the injured Kyle Busch, who suffered fractures of both legs in last month's XFINITY opener at Daytona International Speedway. With Busch out indefinitely, Ragan is scheduled to pilot the JGR No. 18 for the next several weeks before returning to his regular ride in the Front Row No. 34.
