Had this happen in a game last week and I am trying to find the rules support.

A came to the line with four players on the LOS to my side. The TE did not go down to a three point stance but was covered up by the SE. The TE then went in motion down the line of scrimmage away from me. He never was more than 5 yards off the LOS while in motion.

My question is, can the TE go in motion there? I've flipped through the rule book and I cannot seem to find anything on this. I'm sure it is there I'm just missing it. If the TE can go in motion, he would have to satisfy the 5 yards behind the LOS requirements, correct?
