It's actually his spur on the back of his boot from the picture you posted.
If you look at your pic, there's a silver band around his heel, it's supposed to be on the back of it and alignment-wise, with the point (slightly longer edge) at the top near his calf and the shorter end at his foot. (I think the leg he has over the back of the griffin shows which way to further confirm it.)

EDIT: Ninja'd and just spotted you noticed it's the spur. (For some reason I can't delete this post though.)
