Wood's headaches may be caused by ADD medication

A bad reaction to Attention Deficit Disorder medication may be the cause for headaches Busch Series driver Jon Wood suffered this weekend at the Dover International Speedway, forcing him to give up his ride to another driver for Saturday's race.

Furthermore, the driver's apparent and ongoing ADD is a misdiagnosis, according to a statement from his father Eddie Wood, co-owner of Wood Brothers/JTG Racing.

"Jon Wood got out his car on Friday following Busch Series practice by his own choice due to headaches and not feeling well," Eddie Wood said in the statement issued Sunday. "He is presently being evaluated by doctors for these symptoms. It is believed at this time that he has been misdiagnosed with ADD and is experiencing adverse reactions to the prescribed medications."

Jon Wood, 25, was not at the track Sunday, but crew chief Scott Zipadelli said the driver was resting at home and will return to the Busch car when he is well.

"When Jon feels 100 percent, he's on top of his game and we are consulting with physicians to determine when that will be," said Zipadelli, who will fill in for crew chief Michael "Fatback" McSwain on the Wood Brothers' No. 21 Ford for Bill Elliott in Monday's rain-delayed Cup Series race. McSwain's wife is having a baby.

Wood, who began complaining about his headaches Friday morning, is 25th in the Busch Series point standing and prior to Saturday had not missed a Busch race since beginning full time in 2005, 83 races ago.

Cup Series veteran Mark Martin practiced Wood's No. 47 Ford and Travis Kvapil piloted the ride for Saturday's Dover 200. Kvapil experienced radio troubles, crashed out and finished 31st.

Initially, Wood's headaches were believed to be from a string of hard crashes on the track so far this season.

In 13 starts, Wood has one top-10 finish, has been taken out of three races because of accidents and has crashed two cars in practice.

But when asked if the ADD medication was the cause for any of the crashes or affected his performance, Zipadelli said no, there is no correlation between the two.

Competition officials for NASCAR were made aware of the situation and said whether Wood has ADD or not, it's not an issue for them at this point.

Ramsey Poston, NASCAR's managing director for corporate communications, said NASCAR is "100 percent behind the Wood Brothers" organization and at no point in time this weekend was Wood under suspicion for substance abuse.

When the driver returns, Poston said Wood will need to be cleared by his physician or a NASCAR physician in order to race again.
