The stolen Heisman, the highest award in collegiate football, was a duplicate given to the university in 1968 following Simpson’s performance as the school’s running back.
Police are investigating the theft, they said, but did not release further details, such as where the trophy was found.
Simpson, a retired Pro Football Hall of Fame running back for the NFL’s Buffalo Bills, was acquitted in 1995 of murdering his former wife and her friend Ronald Goldman in Los Angeles. He later lost a wrongful death case brought by the victims’ families.
Simpson is now in prison on a 2008 armed robbery conviction related to the robbery of two sports memorabilia dealers at a Las Vegas hotel.
