<P> The number of wild - card qualifiers was expanded to two per conference in 1978--the divisional winners were granted a bye week while the wild card teams played (hence the origin of the phrase "Wild Card Round"). Like wild card teams before, the wild card game winner played the #1 seed, or the #2 seed if they and the #1 seed were divisional rivals . The playoffs were expanded again to three wild cards per conference in 1990 (or 12 teams total, which remains now) with the lowest ranked divisional winner losing its bye . Following the addition of the Houston Texans in 2002, the league added a fourth division to each conference . The league decided not to change the number of playoff teams, and thus the number of wild card qualifiers was reduced to two per conference, with the two lowest ranked divisional winners not receiving byes . The term "Wild Card Round" continues to be used for the opening weekend of NFL playoffs, even though that weekend has involved both wild card and non-wild card teams since 1990 . </P> <P> As of the start of the 2018 season, there has never been a meeting of two wild card teams in the Super Bowl . </P> <Ul> <Li> 1980 Oakland Raiders--Super Bowl XV (played in 1981) </Li> <Li> 1997 Denver Broncos--Super Bowl XXXII (played in 1998) </Li> <Li> 2000 Baltimore Ravens--Super Bowl XXXV (played in 2001) </Li> <Li> 2005 Pittsburgh Steelers--Super Bowl XL (played in 2006) </Li> <Li> 2007 New York Giants--Super Bowl XLII (played in 2008) </Li> <Li> 2010 Green Bay Packers--Super Bowl XLV (played in 2011) </Li> </Ul> <Li> 1980 Oakland Raiders--Super Bowl XV (played in 1981) </Li>
