RGIII scheduled for knee surgery, says is reporting that Robert Griffin III will have surgery on his injured knee.

The Redskins rookie quarterback suffered a tear to his lateral ligament and ACL, sources tell ABC7 News.

The surgery will repair the damage to his LCL, says. His "anterior cruciate ligament" will also be evaluated during the surgery. The evaluation will determine whether more surgery is necessary. According to the league's website, the surgery is currently scheduled for this week.

The Washington Post reported Monday that an MRI exam suggested that Griffin suffered a partial tear of his ACL and LCL, according to several sources.

Griffin also tore his ACL while playing for Baylor in 2009.

A torn ACL typically requires a rehabilitation period of nine to 12 months, although some players don't return to full health until their second season after the injury. On the other hand, one of this season's most remarkable stories was Adrian Peterson, who returned about eight months after tearing an ACL and nearly broke the NFL's single-season rushing record.

Head coach Mike Shannahan is being strongly criticized for his decision to leave the rookie in the game Sunday—a decision the coach says he left up to Griffin himself.

Already playing with a heavy black brace in his third game since spraining a lateral collateral ligament, Griffin hurt the knee again when he fell awkwardly while throwing a pass in the first quarter of Sunday's 24-14 playoff loss to the Seattle Seahawks.

Griffin stayed in the game, but he was far from his usual self, clearly favoring the knee and unable to run with the world-class speed that helped define his play early in the season.

Then, in the fourth quarter with the Redskins trailing by seven, the knee buckled the wrong way when Griffin tried to field a bad shotgun snap. The Seahawks recovered the fumble deep in Washington territory, setting up a short field goal that helped put the game out of reach. Griffin was done for the evening.

Shanahan said he thought he made the "right decisions" to keep Griffin in the game and that it would be "crazy" to think he would purposely sacrifice Griffin's career to win a game. He said he did not talk to team doctors initially after Griffin was hurt in the first quarter, instead relying on Griffin's word.

"I went up to Robert. I said, 'You OK?'" Shanahan said. "And he said, 'I'm fine.'"

Then there is the issue with the grass at Fed Ex Field—many calling it an embarrassment and by far the worst in the league—could have played a role in the injury.

Early in the season, head coach Mike Shanahan was fined for lying about Griffin's concussion. Then, there were the conflicting reports over the last few weeks about whether a doctor had cleared the quarterback to play.

None of the misinformation surprised ESPN 980 host Kevin Sheehan.

“Coaches in the NFL lie all the time. Lie about injuries. They're evasive in all of their answers,” he says. “Especially during the week. It’s the competitive advantage.”
