An asst. coach for a WNBA team severed two arteries in his arm while allegedly punching through glass in a domestic violence incident and was rushed to the ICU ... TMZ Sports has learned.
The man at the center of the incident is Todd Troxel -- an assistant coach for the Phoenix Mercury. He's also famously worked with NBA stars like Yao Ming and Marko Jaric.
Todd was hospitalized on Dec. 1 -- and while he was there, he told cops that he accidentally sliced his arm on broken glass while putting up Christmas lights.
