Robert Griffin III, more popularly known as RGIII of the Washington Redskins, is soldiering on against the Seattle Seahawks despite a knee injury. Fans are worried when it appeared as though he had re-injured his knee during the game Sunday.

RGIII and RG3 quickly got listed on Twitter's worldwide trending topics. Sports fans talk about his knee injury and how the game would be different if he was not hurt. The rookie seemed to have worsened his right knee's condition during a rollout in the first quarter. He was seen limping before Redskins coach Mike Shanahan sent him to the locker room.

Meanwhile, sports surgeon Dr. James Andrews revealed to USA Today he never cleared RGIII to re-enter the game against the Ravens last year after his knee got injured.

"He didn't even let us look at him," Andrews claimed. "He came off the field, walked through the sidelines, circled back through the players, and took off back to the field. It wasn't our opinion," he said.

Shanahan, however, had said the day after the Redskins vs Ravens game that Dr Andrews had cleared RGIII to return.
