Washington Redskins quarterback Robert Griffin III says he went through Wednesday's practice at full speed, but still does not know whether or not he'll play on Sunday against the Philadelphia Eagles.

Griffin said that he went through the entire practice at full speed and that his receivers told him that his passes had "zip," but it was not his decision about whether or not he'll play in the 8-6 Redskins' key Week 16{ } match-up.

"I'm ready to play whenever they want me to play," Griffin said after practice. "I always expect to play."

Team officials say they will continue to evaluate Griffin's condition through the rest of this week's practices. Coaches say that if he doesn't suffer any setbacks due to the injury, he'll play Sunday.

The Redskins precocious rookie didn't play in last Sunday's 38-21 win over the Cleveland Browns while still nursing a sprained right knee that he suffered a week earlier against Baltimore.

In his place, fellow first-year QB Kirk Cousins threw for 329 yards and two touchdowns in the victory. It was the team's 5th straight win, which pulled them into a three-way tie for first place in the NFC East.

Griffin said that despite being disappointed in not playing, he learned a lot "as a spectator" in Cleveland.

"As a player, I'm not going to say sitting out a game is the best thing," Griffin said. "They're trying to protect me from myself."

Washington's playoff chances hinge on their final two games, as they, the New York Giants and Dallas Cowboys all hold 8-6 records going into the season's final two weeks.

While the Redskins play the Eagles Sunday, the Cowboys host the New Orleans Saints while the Giants visit Baltimore. Dallas then visits Washington to finish the regular season for both teams.
