I know that if a kickoff goes over 10 yards it is a live ball and if a kickoff lands in the endzone without being touched by the receiving team, the receiving team gets the ball on the 25 (a touchback), but what is the rule where the kickoff hits in the field of play, say, on the 5 yard iine and rolls into the end zone without being touched,,,is that an automatic touchback or is it a live ball? Can it be recovered by the kicking team for a touchdown?
