You've seen the "butt fumble." Now, marvel at the "butt punt."
In one of the weirdest plays you'll ever see in the NFL, Miami Dolphins punter Thomas Morstead lined up to kick from his own end zone late in a 21-17 game against the Buffalo Bills. Morstead received the snap cleanly, and got off a booming punt -- directly into the rear end of Trent Sherfield, his blocker.
The ball, unsurprisingly, went backward -- out of the end zone, in fact, for a safety. Suddenly, the Dolphins were in a much worse position -- instead of having to prevent Josh Allen and Buffalo's high-powered offense from scoring a touchdown with only 1:33 remaining, they now had to worry about a go-ahead field goal.
