Buccaneers punter Bryan Anger had a fantastic game in his team's win 26-24 win over the Giants on Sunday. Anger punted four times for an average of 49.8 yards, including two gems—he had a 53-yarder downed at the 3-yard line and a 62-yard boomer downed at the 11.
The NFL took notice of this performance and apparently wanted to make sure no funny business was going on. So, the league did what leagues tend to do when this sort of thing happens: they drug tested Anger the morning after the game.
As mentioned previously, this isn't all that uncommon in professional sports.
