Los Angeles Lakers guard Isaiah Thomas will undergo arthroscopic right hip surgery on Thursday, the NBA club announced Wednesday, ending a difficult season because of the nagging injury. No timetable for recovery is expected until after the procedure, but Thomas will become a free agent with major questions surrounding him after being sent from Boston to Cleveland to the Lakers since August. Thomas has averaged 15.2 points, 2.1 rebounds and 4.8 assists this season in 32 total appearances for the Lakers and Cleveland, which obtained him from Boston in the deal that sent Kyrie Irving to the Celtics.
