Question: can you score on a two point conversion interception

Answer: Yes, 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.
