Chargers coach Mike McCoy has refuted star tight end Antonio Gates' comment that quarterback Philip Rivers has a severe rib injury.

Rivers was injured twice in Sunday's 13-6 victory against winless Oakland but remained in the game.

Afterward, while commenting on Rivers' toughness, Gates said: "For those who don't know, he's been dealing with a rib injury, a very severe rib injury. So he's been toughing it out these last three, four weeks."

Asked Monday about Gates' comment, McCoy said: "Philip's never missed a snap in practice and he hasn't been in treatment with James, so I would not say severe injury." McCoy was referring to trainer James Collins.
