The NFL players' union does not plan a formal investigation into how the Washington Redskins medical staff handled Robert Griffin III's knee injury.
The NFL Players Association said Friday that they were satisfied with a report received from the Redskins detailing the procedures used by team physician James Andrews and other staff on the sidelines.
Griffin had reconstructive ACL surgery Wednesday after reinjuring his right knee in Sunday's playoff loss to Seattle. He also strained a ligament in the knee last month against Baltimore.
The NFLPA's informal inquiry focused on the quality of medical care Griffin received. The union does not have authority to investigate coaching decisions - including whether Redskins coach Mike Shanahan should have left Griffin in either game after it was clear the quarterback was hurt.
