Former Dolphins wide receiver Mark Duper was released from jail Thursday, charged after police say he beat his 17-year-old son during a series of fights at their Jacksonville home.

Duper, 54, was arrested Wednesday on one count of felony child abuse and spent the night in jail. Police records say the confrontations began when Duper learned his son, Marcus, had sent a threatening text to Marcus’ former girlfriend. Duper reportedly attacked his son three times and knocked him out twice.

The Associated Press reports that former Dolphins defensive end Hugh Green witnessed the fights and broke up two of them. Green told the AP that Marcus Duper had started the fights, thinking he could “beat his father.”

After the first confrontation, according to the police report, Duper told his son to leave the house. When Marcus returned to get a jacket, another fight ensued. Both ended with Marcus Duper losing consciousness.

“I saw Mark defending himself after a young son was defiant,” Green said.

The elder Duper told The Miami Herald that the fight was “a family matter.”

“This is not an open book. I have to deal with this within my family,” he was quoted by the Herald as saying.

Duper, who has twice been arrested on domestic battery charges since 2003, played for the Dolphins from 1982 to 1992. A three-time Pro Bowl selection and a two-time All-Pro, he legally changed his name to Mark Super Duper.
