In the closing minutes of the Cardinals-Ravens game, Adrian Wilson was called for a personal foul when he delivered a hard hit to Ravens tight end Todd Heap. In explaining the foul, the referee made mention of Heap being a "defenseless receiver". Can you explain this "defenseless receiver" rule? -- Matt, Freehold, N.J.
All players in virtually defenseless postures are protected from unnecessary hits by the defense, which include helmet-to-helmet contact, helmet-to-body contact, and blows to the head. Intended receivers of forward passes who fail to catch the pass are considered to be in a defenseless position immediately after the pass is missed. If the pass is caught, all of these restrictions are off, unless in the opinion of the covering official, something unsportsmanlike occurs. In your play, the pass was missed by the tight end and he was unnecessarily hit by the defender. The announcement by the referee was excellent. The microphone is used to explain situations so that the public can understand what happened and why.
