(09-08) 14:30 PDT -- San Francisco General Hospital is asking for the public's help in identifying a man found unconscious and critically injured over the weekend in the city's Union Square.

The man was found at 5 a.m. Saturday with what appeared to be head injuries from a fall, said Rachael Kagan, a hospital spokeswoman.

The man is white, approximately 30 to 40 years old, 5-foot-10 and 165 pounds, Kagan said. He has brown hair and eyes and was wearing Levi's jeans and black leather shoes, but no shirt, when he arrived at the hospital.

He carried no wallet or identification, only a Jeep key and silver house key.

Anyone with information about the man's identity is encouraged to contact the sheriff's office at (415) 206-8063.
