MIAMI -- A frustrated Amare Stoudemire punched a glass casing surrounding a fire extinguisher minutes after the New York Knicks' loss to the Miami Heat, according to a team source. The Knicks power forward suffered lacerations on his left hand which required stitches.

A league source told ESPNNewYork.com that Stoudemire is "almost certain" to miss Game 3 on Thursday in New York and there is a possibility that Stoudemire could miss the rest of the series.

Stoudemire was treated by paramedics and team doctors from both the Knicks and the Heat and was seen leaving the arena with his left forearm and hand heavily bandaged and his arm being supported by a sling. He suffered the laceration on the inside of his palm, on the side of his hand closest to the pinkie.

A source with knowledge of Stoudemire's injury says there is no ligament or tendon damage in the hand.

He punched the glass casing after walking off of the court following the Knicks' 104-94 loss to the Heat.

"He was just frustrated," a league source with knowledge of the incident said.
