CONCORD, N.C. -- Brian Vickers will miss the rest of the 2013 Sprint Cup season after being placed on blood thinners for a blood clot in his right calf.
Michael Waltrip Racing announced Monday morning that Vickers said William Downey put the driver of the No. 55 Toyota on the medication after finding the small clot in a Monday morning examination.
Vickers, who missed the final 25 races of the 2010 season while recovering from blood clots and heart surgery to repair a hole between his atria, said doctors are confident he will be able to resume activity before the 2014 season.
He was scheduled to test Monday at Charlotte Motor Speedway but was replaced by Brett Moffitt.
"If there's anything to be positive about with today's news it's that this is only a temporary setback," Vickers said in a team release. "The timing for this is never good, but I'm glad we'll get it out of the way now and be ready to run for a championship with the Aaron's Dream Machine in 2014."
CAREER: Vickers by the numbers
VICKERS: Signs with MWR for full-time Cup ride
MWR said it would name a replacement later.
"We were just informed this morning and our concern is for Brian's health," MWR co-owner Rob Kauffman said. "Anything else will be worked out in due course."
The news also will affect Joe Gibbs Racing, which fields a full-time entry for Vickers in the Nationwide Series. That series doesn't race this weekend.
Two-time Daytona 500 champion and team co-owner Michael Waltrip already was scheduled to drive the No. 55 at Talladega Superspeedway this weekend. Vickers had taken over the No. 55 virtually full time in August after Mark Martin was named as the replacement for injured Tony Stewart for most of the rest of the season.
Vickers already had been announced as the full-time driver of the MWR Aaron's-sponsored Camry in a multiyear deal starting in 2014.
Vickers last raced full time in NASCAR's premier series in 2011 and lost his ride when Red Bull Racing was shuttered. He joined MWR on a part-time schedule last year and ended a 75-race winless streak with a July 14 victory at New Hampshire Motor Speedway.
In 22 races with MWR in 2012 and 2013, Vickers owns five top-five and 10 top-10 finishes.
