Cowher got a break as a Bird

From the Rocky Mountain News:

Former players do win more respect
On a list of things that can be on a coaching résumé, Bill Cowher has something none of his peers has.
He has fractured the leg of a player in an NFL game who later became a fellow coach.

Cowher, as a Philadelphia Eagles special-teams player, once broke a leg of then-Chicago Bears cornerback Jeff Fisher on a punt return.

"I still probably owe him for that," said Fisher, the coach of the Tennessee Titans since 1994.
