<P> In American college, professional, and Canadian football (as well as, for a significant period of time, the Arena Football League, where missed extra points are rebounded back into the field of play), a conversion attempt where the defense gains possession of the ball can be returned by the defense to the other end zone to give the defensive team two points . The team that scored the touchdown then kicks off as normal . This is rare because of the infrequent use of the two - point conversion and the rarity of blocked conversion kicks, combined with the difficulty of returning the ball the full length of the field . It has proven the winning margin in some games . Only once has a player scored two defensive two - point conversions in a game: Tony Holmes of the Texas Longhorns in a 1998 Big 12 Conference game against the Iowa State Cyclones on October 3 . </P> <P> On May 19, 2015, the NFL owners adopted a proposal to permit a defensive two - point conversion for the 2015 season . </P> <P> Stephone Anthony of the New Orleans Saints became the first NFL player to score a defensive two - point conversion; he returned a blocked extra point kick from Graham Gano of the Carolina Panthers on December 6, 2015 . </P> <P> On December 4, 2016, Eric Berry of the Kansas City Chiefs became the first NFL player to return an interception for a defensive two - point conversion; it was thrown by quarterback Matt Ryan of the Atlanta Falcons . </P>
