Ireland legend Brian O'Driscoll has called for a change in the laws that would stop scrum-halves being disrupted by players within the ruck, citing an example from Wales' heavy defeat to Scotland.
The former Ireland centre highlighted an incident from Wales' 35-7 defeat at Murrayfield on Saturday which saw Scottish prop Zander Fagerson take advantage of the law and win a turnover for his side by knocking Tomos Williams' arm while he was getting the ball away from a ruck.
Ironically, at the next ruck, Williams did the same to opposite number Ben White to disrupt the Scottish scrum-half's pass.
