HUNTERSVILLE, N.C. (AP) - Joe Gibbs Racing President J.D. Gibbs is undergoing treatment for "symptoms impacting areas of brain function."
The 46-year-old Gibbs is the oldest son of team owner Joe Gibbs, the Hall of Fame coach who won three Super Bowls with Washington.
The team said in a statement on Wednesday that J.D. Gibbs has undergone a series of tests since experiencing "speech and processing issues." No diagnosis was released, but JGR says doctors believe the symptoms are related to "head injuries likely suffered earlier in life."
JGR says no specific injury has been identified.
J.D. Gibbs played football and had a brief career as a race car driver. He also snowboards, mountain bikes and participates in other extreme sports.
His presence at tracks is expected to be limited while undergoing treatment.
