NFL Commissioner Roger Goodell says he doesn't have a problem with the way the Washington Redskins' medical staff handled Robert Griffin III's knee injury.
Nevertheless, he's anticipating changes in the way injuries not affecting the head are evaluated on the sideline.
Goodell was in Denver for Saturday's Ravens-Broncos playoff game.
Griffin had reconstructive ACL surgery Wednesday after reinjuring his right knee in last Sunday's playoff loss to Seattle. He also strained a ligament in the same knee last month against Baltimore.
That raised questions about whether Redskins coach Mike Shanahan should have let Griffin in either game after it was clear the quarterback was hurt.
Goodell said it was a ''medical decision'' and noted Griffin had no problem with it, either.
''Now, people can argue whether it was the wrong decision, but it was a medical decision and that's what we want it to be,'' Goodell said.
