   It is far less likely but you can get one form of kickback when using a sled.

   Most kick back occurs when ripping against the rip fence, when the piece of wood trapped between the fence and the blade is first lifted by the upward moving teeth at the back of the blade until it is caught by the top of the blade and thrown forward.

   The fact that there is no trapped piece reduces the chance that a cutoff piece will be thrown but it is still possible for a loose cutoff to be grabbed and thrown by the blade. The most likely scenario would be for a small loose cutoff sitting on the right side of the sled to be caught by the blade when you pull the sled back after making a cut.

   This is one of the situations where a low riving knife offers a great deal of protection.

   Thanks!  That makes sense.
