Robert Griffin III’s surgically repaired right knee responded favorably after the quarterback began the latest increase in activity of his rehabilitation program.

According to a person with knowledge of the situation, Griffin this week began making cuts for the first time since his Jan. 9 surgery to repair the ligaments that he tore in his right knee in Washington’s playoff loss to Seattle. Each week has brought with it additional strides of improvement for the quarterback.

This week featured drills in which Griffin sprinted to the left and right, and then cut to the opposite direction. He also did other change of direction drills. Griffin went through those types of workouts for three consecutive days. There were no indications of setbacks of any kind, said the person, who spoke on condition of anonymity because they weren’t authorized to speak for the team.

Griffin began on-field running earlier this spring. Each week during Washington’s offseason program, the quarterback was permitted to increase his activity. He began explosive sprinting two weeks ago, but hadn’t been allowed to make cuts.

The cuts and change of direction drills ranked among the final physical items left unchecked on the quarterback’s to-do list. Griffin is hoping to return to the field by the start of the Redskins’ training camp on July 25. He has yet to receive clearance from doctors to practice, however.

Griffin is expected to spend the next five weeks further strengthening his knee and continuing to do the same drills. He will continue to train at Redskins Park for at least the next week.

In his most recent media availability – June 11 at the Redskins’ minicamp – Griffin outlined the next month: “After [making cuts], it’s just everything over and over. I’ll continue to work out in the weight room over the next four or five weeks. I continue to keep sprinting and just get more and more comfortable. And then whatever I feel like I have a deficiency at, I make sure I fix that. There’s exercises you can do to help with that.”

Griffin has two significant checkups with team orthopedist James Andrews in the next five weeks. The surgeon will evaluate the quarterback’s knee early next month, then will examine it once again just before the start of training camp to determine if Griffin is indeed ready to take the field right away, or if more rehab is necessary.

Although Griffin has said he expects to be ready in time for the start of camp, Redskins Coach Mike Shanahan has remained noncommittal.

Asked on June 12 about the return date, the coach said, “The big thing is when we go to camp. He’ll get a physical and see where he’s at. … When that [return] date is, I don’t think anybody knows. The doctors are going to look at him and tell us when he’s ready to practice. When he is, we’ll see what he can do.”
