Robert Griffin III, the Washington Redskins rookie quarterback, is confident he will overcome a sprained right knee to be fit to face the Philadelphia Eagles and guide his team to the <a href="gopher://topicL3RoZW5hdGlvbmFsL1N1YmplY3RzL05GTA==" inlink="topic::L3RoZW5hdGlvbmFsL1N1YmplY3RzL05GTA==">NFL</a> play-offs after returning to training. "I was able to go through a full practice. That felt good," Griffin said. "I was able to get back out there and get ready. I feel really good. It has been a gradual improvement. It just takes rest and time. It was a matter of time." Griffin missed last week's 38-21 triumph at the Cleveland Browns, where the Redskins stretched their win streak to five games, the club's longest since 2005, and moved into a share of the NFC East division lead at 8-6 with the Dallas Cowboys and the New York Giants. The Redskins control their own destiny and will capture the division crown, and their first play-off berth since the 2005 season, by winning at Philadelphia (4-10) on Sunday and a week later at home against Dallas. "That's the mission we're still on. Guys can't get happy now. We still have one game to work on and another game after that," Griffin said. "We'll take them as far as momentum goes, but we're not thinking about those games or the win streak when we go into a game each week." Washington began the win streak with a 31-6 triumph over Philadelphia last month, which was followed by a 38-31 victory at Dallas. Griffin, whose replica jersey is the best selling in the NFL this season, said there are no strained relations with team doctors or coach Mike Shanahan for benching him last week when he felt he could have played. "They are going to try to protect me from myself at all times," Griffin said. "I'm ready to play when they want me to play. Whenever they say go, I'll be ready to go. I think I have to prove it to them on the field, running around and making the plays. I always expect to play. "They are going to keep playing it by sight, keep watching me and see what they think the best progression is for me." The Redskins, who have reached the play-offs only once since 1999, began the season 3-6 but have turned the season around under Griffin, who has thrown for 2,902 yards in his first NFL campaign. "We said don't freak out, don't jump ship - just because we started 3-6 doesn't mean we can't do what we want to do and still win," Griffin said. Supporters were nervous when Griffin went down with a knee injury but rookie Kirk Cousins replaced him and sparked a Washington triumph, then guided the team to victory at Cleveland last week. "It was frustrating for me but once we stepped on the field I was all for the team and all for Kirk," Griffin said. "You can't be a cancer for the team. It was good to see it from the sideline and watch it all week. You can be unhappy about something but you still have to learn. You can still learn a lot sitting around and watching for a week." Despite Griffin's optimism, Cousins is working out as if he will get the call again on Sunday. "I'm still focusing and preparing on my opportunity to play. I have to be ready to go," he said. "I look at this as an opportunity to sell myself to these coaches here and 31 other coaches. sports@thenational.ae Follow us
