Sorenson will drive for Braun at Charlotte Motor Speedway (May and October), Daytona Superspeedway (July), Michigan International Speedway (August) and Atlanta Motor Speedway (September).
"This sport is our passion and we are all racers at heart.. However, what Brian Vickers is facing now is bigger than racing. He has been a member of the Braun Racing family since 2007 and has been very important to the success of our company. He will always have a seat in one of our race cars,” team owner Todd Braun said according to NASCAR.
“Everyone at Braun Racing wishes him the absolute best as he continues his treatment and works towards a return to competition in 2011."
Vickers is suffering from blood clots, a condition which has the potential of causing stroke, heart attack and even pulmonary embolism. The doctors don't yet know what caused Vickers' clots, which are located around his lungs and legs.
"Brian is probably one of the most talented drivers that I've worked with and has been a very valuable part of this team and its success," crew chief Trent Owens added. "We are obviously more concerned about his health and him getting better than we are about his racing. He will be missed but we look forward to working with him again in the future."
