NFL suspends Chargers SS Gregory for 4 games

SAN DIEGO (AP) – The NFL says San Diego Chargers strong safety Steve Gregory has been suspended without pay for four games for violating the NFL policy on performance-enhancing substances.

The suspension begins with Sunday's game at Oakland. The NFL isn't saying what substance Gregory tested positive for.

Gregory says in a statement that he was “completely shocked” to find out about the positive test from May. He says he has never knowingly used any form of performance-enhancing substance, but that he's responsible for everything that goes into his body.

Gregory says he appealed the suspension.
