Nic Cage jumped to his son Weston‘s aide yesterday moments after the 20-year-old got into an insane brawl with his trainer … causing cops to have him taken to a local hospital for mental evaluation.

As we first reported, after cops arrived at the Hollywood restaurant where Weston went off, they strapped him to a gurney and placed him in an ambulance, fearing he was unstable.

In the photo, you see Weston in the ambulance, wearing his unmistakable Thor-themed wedding ring.
