Junior Owen Thomas, one of the University of Pennsylvania’s recently-elected football captains, was found dead in his off-campus apartment around 2 p.m. this afternoon.

The Allentown, Pa. native passed away from unknown causes, but the Daily Pennsylvanian reports that no foul play is suspected. Thomas, a second-team All Ivy selection at defensive end this past season, recorded a team-high six sacks—good for second in the league—and helped lead the Quakers' defensive unit to No. 1 in the nation in total defense and scoring defense, according to the Penn Athletics website.

Thomas, whose older brother Matt played football for the Quakers and graduated in 2002, was enrolled at Wharton.
