Normally I would agree wholeheartedly with the rolling around comments, I was taught the same as you WB, if they are still get there ASAP if they roll half way down the pitch there's unlikely a lot wrong with them. Eredivisie over the weekend - player rolled 27 times (and yes I counted), ref carried on - VAR intervened and called for OFR. It was on the refs blindside and looked innocuous in real time plus the 27 rolls! Viewing on replay it was a nasty, snidey, kick to the thigh with enough force that several of the stud marks left behind were bleeding. Always an exception to the norm!
