A man was punched and knocked unconscious during a game of disc golf at Morley Field in Balboa Park over the weekend.

The violent confrontation Saturday evening was caught on cell phone video.

Dante Mena said he has been dealing with a lot of pain after what was supposed to be a fun afternoon playing disc golf with friends at Morley Field on Pershing Drive.

"I saw a limb fall out of the tree, which isn't that un-normal but then I heard more limbs breaking," Mena said.

Mena told NBC 7, that when he noticed two men climbing in a tree. He said one of the men was intentionally breaking off branches.

"He was continuing to just break the trees apart," said Mena's friend, Zander Daniels. "So my friend Dante told this guy to cut it out."

Cell phone video appears to show the suspect and his companion confronting Mena and then knock him down.

"Both of Dante's hands are occupied, there's no way to defend himself and the guy just punches him in the face," said Daniels.

Mena was knocked unconscious. He suffered a shattered cheek, broken nose, bleeding from his eye and stitches inside his mouth.

Now, Mena’s family and friends are sharing the video in hopes that man is caught so this doesn't happen to anyone else.

"It's sad that this happened and it happened so randomly and be so vicious," said Mena’s wife, Karen.

The suspect has been described at 5-feet 7-inches in height, 150 pounds, with black, shoulder length hair and a goatee. He was wearing a dark blue t-shirt at the time of the assault.

At this time, no arrests have been made.
