A former high school teacher and volleyball coach will spend two years in prison for having sex with three underage players.

A judge also ordered Steven Antony to register as a sex offender Monday.

Antony admitted to having sex with three teenage members of the Sunstorm Volleyball Club, an after-school program in Vista.

Antony was also a physical education teacher at San Pasqual High School, but none of the victims were students there.
