Miami Gardens police spokesman Bill Bamford said Tuesday that John Langsett was stabbed outside Land Shark Stadium on Monday night after an argument started while he was negotiating a ticket sale.
Police say Hamin Basim Ansar pulled out a pocket knife and stabbed Langsett in the chest and back of the head. The 51-year-old Ansar was arrested and charged with attempted second-degree murder.
Langsett was released from the hospital Tuesday morning.
It was not immediately clear whether Ansar had an attorney. He was being held at a jail and his bond has not been set.
