Sunday's N.F.L. action produced one of the stranger ways a player can be tackled...  by their own junk!

In Sunday's game between San Francisco and St. Louis, 49ers tight end Vernon Davis caught a pass and was eventually brought to the ground by the defender who grabbed onto his crotch.

Davis later tweeted that there should be a rule change made.
