Tampa Bay Lightning prospect Adam Erne will undergo wrist surgery on Thursday, Erne announced via his official Twitter account Wednesday night. Erne, the team’s second-round pick in 2013, was held out of skating drills at last week’s prospect development camp because of the wrist injury and flew to Cleveland for an examination at the Cleveland Clinic on Monday. After undergoing testing and evaluation, the surgery was recommended and will be performed by Dr. Tom Graham, who also performed the wrist surgery on goaltender Ben Bishop in May. The extent of the injury and an exact time table for his recovery will not be determined until after the procedure is performed, though Lightning general manager Steve Yzerman said the initial prognosis is Erne will need eight weeks unless more damage is discovered during the surgery.
