September 22, 1974 -- Denver hosted the Pittsburgh Steelers in what would be the first game played under the NFL’s new "Sudden Death" overtime rule. QB Charley Johnson had led the Broncos to a 21-7 1st quarter lead and a 21-14 halftime lead. Pittsburgh scored twice in the third to Denver’s single score to force a 28-28 tie at the end of three quarters. The Steelers took the lead 35-28 in the fourth but Denver tied it at 35-35. The game went into the first ever overtime period. Neither team scored, preserving the tie. The most notable moment in that overtime period came when Denver safety Billy Thompson blocked a field goal attempt which would have given Pittsburgh the win.
