CONCORD -- Intended Mt. Diablo school board candidate Attila Gabor has withdrawn from the November race, citing health concerns.

This leaves incumbent Sherry Whitmarsh and challengers Ernie DeTrinidad, Brian Lawrence, Debra Mason and Barbara Oaks vying for two open seats. Incumbent Gary Eberhart is not seeking re-election.

Gabor had taken out election papers, but did not file them by the Aug. 15 deadline. He had announced his intention to run before the filing period began and had been endorsed by the Mt. Diablo teachers' union, along with Lawrence.

The union announced Wednesday that it has endorsed Oaks in Gabor's place.
