Half of Amar'e Stoudemire's hand was "hanging off" after punching the glass enclosure of a fire extinguisher on Monday, according to a source.

"He didn't haul off and punch the glass; he hit it out of frustration," a person who witnessed the incident told Broussard. "He kind of slapped it, but with a closed fist. He said he thought it was plastic instead of glass. 

"Half of his hand was just hanging off. It was really bad. Blood was just squirting out. That's why they had the paramedics come in, because they thought he might have punctured an artery because of how much blood was coming out."
