Fathers sometimes have no choice but to discipline their children -- but rarely in the way that unfolded this weekend in the NFL.
Packers guard Jon Runyan Jr. received a letter from his father Jon Runyan, the NFL's vice president of football operations, who notified his son that he has been fined $5,215 for leg whipping an opponent during the first quarter of Green Bay's loss last Sunday to the Giants in London.
In the letter, the senior Runyan also warned his son that "further offenses will result in an escalation of disciplinary action, up to and including suspension.
