When asked Sunday night for an update on his son’s right knee, Robert Griffin III’s father answered with a single declarative sentence that was both stark and descriptive: “Knee,” Robert Griffin Jr. said in a text message, “is better than yours and mine.”
And with that — plus an earlier tweet from RGIII himself (“Your positive vibes and prayers worked people!!!!”) and the official word from the Redskins (a sprained knee, but no torn ligaments) — the denizens of the greater Redskins Nation could sleep soundly, knowing that, barring something unforeseen, the Redskins’ rookie phenom could quarterback another game this season.

The Redskins announced Sunday night that the MRI conducted on Griffin’s injured right knee showed that no tears in his ACL or MCL. The team said Griffin has a sprained knee.

“Everything is clear. He has a knee sprain.” team spokesman Tony Wyllie said Sunday night. Asked if that meant there was no torn ACL or MCL, Wyllie said, “correct.”

There is unlikely to be any further word from the Redskins until Coach Mike Shanahan’s 3 p.m. news conference Monday. But before departing Fedex Field Sunday to undergo the MRI, Griffin himself addressed the possibility of a “clean” MRI and how that might affect his ability to play next Sunday at Cleveland.
“If it’s anything else [besides a tear], like I told Coach, I’ll fight through it and be playing next week,” he said.
