E! News has learned that Mark was coming from a protective parental place; he came down in response after seeing his son's headgear got ripped off by his opponent and the referee not calling it. In addition, the actor and Kelly, who also watched the event with him, were shocked that the referee wasn't calling Joaquin getting clubbed in the head several times.
According to TMZ, Joaquin ultimately lost the match.
The teen is Mark and Kelly's youngest of their three children.
The Riverdale actor and LIVE! With Kelly and Ryan co-host are also parents to son Michael Consuelos, 22, and daughter Lola Consuelos, 18.
