Heat player Haywood Highsmith was involved in a car accident following Tuesday night's game in Miami ... a crash that reportedly left one man in critical condition with a partially-amputated leg.
The Heat say 27-year-old Highsmith -- an undrafted free agent out of Wheeling University in 2018 -- got in the wreck heading home from their contest against the Orlando Magic, in which he recorded three minutes of action in the 121-95 win.
According to local reporter Andy Slater, Highsmith hit a man who was helping another driver that was stuck in the middle of the road.
