J.D. Gibbs beginning treatment for symptoms impacting brain function

"All members of the NASCAR and France family extend our thoughts and prayers to J.D. Gibbs and his loved ones," NASCAR chairman and CEO Brian France said in a statement released minutes after Wednesday's news about Gibbs. "We've all watched J.D. grow up within our community, and he always has represented himself, his family, the entire Joe Gibbs Racing organization and NASCAR with the utmost professionalism, enthusiasm and energy. We wish him the best during this time and eagerly anticipate his recovery."

Named president of JGR in October 1997, Gibbs has overseen the organization's expansion from a single-car team to its current four-car stable of NASCAR Sprint Cup Series teams. In addition, JGR has grown to include three XFINITY Series teams, a driver development program and, most recently, JGRMX, a motocross operation.

Gibbs has been with JGR since he joined his father, Pro Football Hall of Fame and three-time Super Bowl-winning coach Joe Gibbs, to launch the organization in 1992.

J.D. and wife Melissa are parents to four boys, including their youngest son, Taylor, who was diagnosed with Acute Lymphoblastic Leukemia but is now in remission.

JGR, which entered NASCAR competition in 1993, has won three Sprint Cup championships and currently fields Sprint Cup teams for drivers Denny Hamlin, Carl Edwards, Matt Kenseth and Kyle Busch.

Busch, however, has been sidelined all season with injuries suffered in the season-opening XFINITY Series race at Daytona.
