Medford police are investigating a stabbing that happened over the weekend when two men drinking and smoking pot together challenged one another to find out who was toughest.

Emergency room crews at Rogue Valley Medical Center called police at about 3:30 a.m. Saturday to report that they were treating a man with a stab wound.

The stabbing victim, who turned 43 on Sunday, was a homeless man who had recently befriended the suspect, Medford police Lt. Tim Doney said. The suspect asked his new acquaintance to stay with him at his west Medford home.

The two were drinking and smoking marijuana Friday night when the victim began shadow boxing. The other man then challenged him to find out who was the tougher man. Their sparring quickly escalated to slap boxing, then the home's resident pulled a knife and stabbed the victim in the upper thigh, just below the groin, Doney said.

The suspect ran down the street to get a cell phone from a neighbor to call for help, Doney said. He called a friend to drive the stabbing victim to the hospital.

The man was treated and released. Investigators are working with him to confirm the identity of the man who stabbed him and the location of the house where he had been staying, Doney said.
