"Right now Brian is our primary driver so he remains listed for the All-Star Race," a Red Bull racing spokesperson told the source. "He is currently in Charlotte undergoing evaluation and tests from specialists and his physician, Dr. Jerry Petty, so we won't have the final results until later in the week."
The blood clots, located in his legs and near his lungs, have been discovered on May 14, after the driver complained of having some discomfort in his chest. His condition has the potential of causing stroke, heart attack and even pulmonary embolism and was possibly caused by inhalation of carbon monoxide.
"Those tests were conducted including a CT scan. The scan discovered several blood clots in his veins, not his arteries," RBR manager Jay Frye said at the Dover Speedway.
"He was admitted Wednesday evening to the hospital, currently he's being given medication to dissolve the clots. He's been thoroughly tested and given a good clean health. The doctors are not sure what caused the clots or how it happened."
Because of his condition, Vickers missed the Dover race, being replaced by Casey Mears. Mears managed to qualify the No. 83 Red Bull Toyota 39th and only finished 22nd on Sunday. Vickers is currently ranked 20th in the Sprint Cup, with his last achievement being a 10th place at the Showtime Southern 500.
