Brett Moffitt will be driving Michael Waltrip Racing's #55 Toyota this Sunday in the NASCAR Sprint Cup race at Auto Club Speedway in Fontana, California. The team's regular driver, Brian Vickers, informed MWR he has experienced a re-occurrence of blood clots, which will require the 31-year-old driver to begin taking blood-thinning medication and he is not able to race while on the medicine.

Quote from Michael Waltrip Racing: "First and foremost our thoughts are with Brian and his family," said MWR founder and co-owner Michael Waltrip. "He isn't just our race car driver, he's our friend and we know the NASCAR community will continue to rally around Brian. We're fortunate to have Brett Moffitt in our system and marveled at his great drive in Atlanta three weeks ago where he finished 8th."
