Trevor Bayne was "doing fine" Sunday after being released from Carolinas Medical Center-University in Charlotte, NC.
Bayne had been admitted to the hospital Sunday morning after returning home from the Sprint Cup race at Texas Motor Speedway.
Results of tests are expected later this week, but the Daytona 500 winner was admitted to the hospital, apparently because of a reaction to an insect bite on his left elbow.
"Trevor has been treated and released from the hospital and is fine to continue with his daily activities — including driving a race car," said Roush Fenway president Steve Newmark. "Doctors are still waiting for the test results to determine for sure what caused the reaction, but Trevor has been treated, is at home and he is doing fine."
Bayne was not available for comment, but the 20-year-old had tweeted earlier: “Not sure if its a spider bite or a tick bite . . . But either way I’m in a hospital bed with a needle in my arm! #nobueno.”
Bayne began exhibiting symptoms Tuesday. On Friday, he was taken to the infield care center at Texas Motor Speedway, where he was administered antibiotics.
Then, Saturday night, he went to the emergency room after the Roush plane returned to Charlotte, and he was admitted to the hospital.
Bayne finished 17th in the Samsung 500 on Saturday night, matching his Sprint Cup debut at Texas Motor Speedway last November. It was Bayne’s best finish since he won the Daytona 500 in February in only his second career Cup start.
