Vincent becomes the second player from the defending national champions to opt out. Neil Farrell Jr., a projected starter at defensive end, opted out last week, according to reports.
SEC teams opened preseason camp on Monday. The conference intends to play a 10-game, conference-only schedule starting Sept. 26. LSU hosts Mississippi State on that date.
Vincent was LSU's starting nickelback last season and ranked second on the team in interceptions with four. He posted a message of thanks to LSU and its fans on Monday.

Several high-profile upperclassmen have made similar decisions in recent weeks, including Penn State linebacker Micah Parsons, Minnesota wide receiver Rashod Bateman and Miami defensive lineman Gregory Rousseau.
