Police said a fight broke out when 19-year-old Tre' Robertson and several friends showed up at the party uninvited just before 1 a.m. at North Campus Crossing in Greenville.
Robertson told investigators he tried to leave, but a man came up behind him and stabbed him. A friend drove the player to the hospital where he was treated for non-life-threatening injuries.
The investigation continues.
According to Robertson's ECU bio page, he played for Person High School before joining the Pirates. The offensive lineman has yet to see any playing time in Greenville, but did serve as a member of the scout team.
