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 who was stuck in the middle of the road.

The man who was struck remains in critical condition, the report added.

The Heat released a statement on the incident … saying, “Our hearts go out to those who were injured.”

Highsmith will sit out Wednesday’s matchup against the San Antonio Spurs due to “personal reasons.”

Highsmith — who has also suited up in the G League and overseas — has appeared in 37 games this season … averaging 5.8 points and 2.8 rebounds so far. It’s unclear when he is expected to rejoin the team.
