Students, teachers and colleagues are mourning the loss of a beloved Central California high school sports coach who died of injuries sustained in a bicycle accident.

Marion Adams was the Rio Linda High School's track and field coach and multimedia teacher.

The Sacramento Bee reports (http://bit.ly/15A9pjB ) the 59-year-old looked over his shoulder to say goodbye to a student as he rode away after Monday's track practice and crashed into partly open metal swing gate in the school parking lot.

Adams was impaled by the gate arm and was rushed to a nearby hospital, where he died Tuesday of internal injuries.

He graduated from the high school in 1972 and returned as a coach in 2004.

Memorial services in the Sacramento suburb are pending.
