Further tests of Robert Griffin III's right knee injury revealed a partial tear of his ACL and LCL, according to a report.
Medical report: What does this mean for RGIII in 2013?
While Monday's MRI suggested a serious injury, Redskins head coach Mike Shanahan said Griffin will undergo further examination on Tuesday to determine if the MRI shows a new or old injury. Griffin tore his ACL during his sophomore season at Baylor in 2009. According to the report, a source indicated there was still some question whether the ligament damage was a new or old injury.
Griffin, who started Sunday with a sprained LCL, appeared to tweak the injury early in the game against Seattle. He stayed in the game, however, before suffering another injury in the fourth quarter. Griffin fumbled a shotgun snap and as he turned to pick up the ball, his knee buckled and he fell to the turf.
Griffin will be examined by orthopedic surgeon Dr. James Andrews on Tuesday. It's still unknown whether the partial tear would require surgery.
