<P> Safeties are the least common method of scoring in American football but are not rare occurrences -- since 1932 , a safety has occurred once every 14.31 games in the National Football League ( NFL ) , or about once a week under current scheduling rules . On October 21 , 1973 , Fred Dryer , playing for the Los Angeles Rams against the Green Bay Packers , became the only player in NFL History to score two safeties in a single game . A much rarer occurrence is the one - point safety , which can be scored by the offense on an extra point or two - point conversion attempt ; those have occurred at least twice in NCAA Division I football since 1996 , most recently at the 2013 Fiesta Bowl . No conversion safeties have occurred since at least 1940 in the NFL . A conversion safety by the defense is also possible , though highly unlikely ; although this has never occurred , it is the only possible way a team could finish with a single point in an American football game . </P>
