RG3 defends himself as Redskins await knee results

(AP) Robert Griffin III knows he's getting criticized for playing hurt in the Washington Redskins' playoff loss.

On Monday, he offered his latest defense on Twitter.

The rookie quarterback tweeted: Many may question, criticize & think they have all the right answers. But few have been in the line of fire in battle.

The Redskins were awaiting the results of an MRI on Griffin's right knee, which he re-injured twice during Sunday's 24-14 loss to the Seattle Seahawks.

Griffin did not appear in the locker room during the two hours it was open to reporters Monday morning. Teammates defended Griffin, saying it's in an athlete's competitive nature to keep playing as long as possible.
