Washington Redskins offensive coordinator Kyle Shanahan has said that Robert Griffin III is showing daily improvement.

The quarterback, who has been recovering from a knee injury, took his first 11-on-11 snaps on the pre-season earlier this week.

Shanahan told the Redskins' website: "I think it was a better practice all around, for everybody, first of all. It just seemed crisper and I thought [Griffin III] did a better job. I'll look at film when I get up, but it just seemed better.

"It's just a process of getting back. Robert works as hard as you can work. You can't work harder than that. He's done his rehab the right way and that's why he's been able to come back so much earlier than expected.

"Now it's just the grind of getting back, getting the rust off and getting him as many reps as possible without jeopardising anything and he's doing that. He's gotten better each day. I see [his knee] getting better and I think it will get better each week. Hopefully we will get him ready for that first week."

The 2012 offensive rookie of the year is expected to miss the remaining pre-season games.
