I don't work football, but am always intrigued by signals/mechanics among crews.

Can someone tell me what it means when the R (NFL) waves his hands in front of his body in an up and down motion and then points towards the offensive line? At first, I thought it had to do with a player in an 'irregular' number reporting as an eligible receiver, but then I looked at the o-line, and didn't see any irregular numbers on the end of the line.

I saw this happen over the weekend and it's always puzzled me - appreciate the feedback.
