Varga opted to retire from the NFL on Tuesday, John Kryk of the Toronto Sun reports.
Varga suffered a concussion roughly nine months ago, but earlier this month was cleared to return to football activities. Despite previous reports indicating he intended to play during the 2016 season, Varga has now changed his mind and will hang up the cleats, as he doesn't want to risk his future health any further. Varga spent just one year in the league, seeing action in three games, while providing two rushing yards and 18 reception yards.
