Funny Car driver Eric Medlen, injured in a testing accident Monday at Gainesville Raceway, remained in critical condition Tuesday in intensive care at Shands at the University of Florida medical center.

According to Medlen's father, John, doctors are continuing to work to reduce pressure and swelling from what has been characterized as a severe closed head injury suffered when the 33-year-old's car crashed heavily into the guardwall.

Injured NHRA Funny Car driver Eric Medlen survived a delicate, three-hour craniotomy procedure to relieve pressure and hemorrhaging Tuesday evening but remained in critical condition Wednesday at Shands at the University of Florida medical center.

Over the next two weeks, the 33-year-old will remain in a drug-induced coma designed to promote healing.

While medical personnel at Shands at the University of Florida medical center continue to monitor the progress of injured Funny Car driver Eric Medlen, team sponsor BP/Castrol announced Thursday the creation of a special e-mail address at which well-wishers can leave messages of encouragement for the 33-year-old drag racer.

Castrol Syntec, Medlen's primary sponsor in his first three seasons on the NHRA POWERade tour, has announced that it will print and assemble all messages left at the e-mail address getwelleric@castrol.com and present them later to the driver and his family.

Castrol also will make available at NHRA national events and at the upcoming Mid-America Trucking Show (Louisville, Ky.) posters bearing a likeness of the popular driver on which fans can print personal messages. Those posters also will be presented to the Medlen family according to Lori Anne Gola, assistant sponsorship manager for Castrol.

Eric Medlen, 33, who had emerged as one of the most popular young drivers in the NHRA POWERade Drag Racing Series, succumbed Friday afternoon to injuries suffered when his race car crashed into a guardwall during a Monday test session at Gainesville Raceway.

The talented Funny Car driver never regained consciousness. After being treated at the track, he was transported by ShandsCair helicopter to Shands at the University of Florida medical center where medical staff treated him for four days for a severe closed head injury.

"Eric suffered from severe traumatic brain injury with diffuse axonal injury, or DAI," said Dr. Joseph Layon, professor of anesthesiology, surgery and medicine and the chief of Critical Care Medicine at UF. "Survival rates associated with DAI are low.

"On Tuesday, UF and Shands neurosurgery team performed a cranjectomy and removed the front portion of the skull to relieve pressure and attempt to improve blood flow to the brain," Layon explained. "Despite receiving the most aggressive treatment, Eric continued to have uncontrollable intracranial pressure. His body lost the ability to manage its salt and water levels, and he began displaying the complicating factors associated with DAI.

"That is when Eric's family elected to honor Eric's wishes and remove him from the artificial life support systems. Our hearts go out to Eric's loved ones."
