Frerotte played 58 games for the Bills in 1987 and the Super Bowl seasons of 1990-1992, mostly as a reserve and special teams member.
The Snyder-Crissman Funeral Home in Frerotte's home town of Kittanning confirms the death, but says funeral arrangements remain incomplete. Frerotte died unexpectedly at home, and a cause of death was not immediately available.
Frerotte played for Penn State from 1983 to 1987 before signing with the Bills. He suffered a career-ending neck injury after joining the Seattle Seahawks for training camp in 1983.
