ASHBURN, VA. (AP) - Robert Griffin III will get more tests on his injured right knee after an MRI proved inconclusive because of a previous ACL tear.

Washington Redskins coach Mike Shanahan said Monday that the rookie quarterback will travel Tuesday to see orthopedist James Andrews for more examinations.

Griffin tore his ACL while playing at Baylor in 2009, and Shanahan said sometimes an old injury can cloud the results of an MRI.

If Griffin has torn the ACL again, he would likely require a rehabilitation period of nine to 12 months, putting his status for next season in jeopardy.

Griffin reinjured his knee twice in Sunday’s playoff loss to Seattle.

As the Washington Redskins awaited word on Robert Griffin III’s health, teammates defended the rookie quarterback’s decision to keep playing after reinjuring his right knee.

Griffin also chimed in. He did not appear in the locker room during the two hours it was open to reporters Monday morning, but he offered some thoughts on Twitter.

“Many may question, criticize & think they have all the right answers. But few have been in the line of fire in battle,” Griffin tweeted.

The Redskins were expected to announce results of Griffin’s MRI later Monday.

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.

If Griffin had been pulled earlier, the critical turnover might not have happened. And, of course, his knee probably wouldn’t be hurt as badly as it is.

“I thank God for perspective and because of that I appreciate the support from everyone. I also appreciate the criticism,” Griffin tweeted.
