Mick Cleary wades into the debate surrounding the Ospreys' 16th man in The Daily Telegraph
"Yes, there was a huge difference in degree in what Quins tried to pull off last season and what Ospreys did on Saturday at the Liberty Stadium. One was wilful and duplicitous: the other was rash, impetuous and damned careless.
"Mind you, that is to give Ospreys the benefit of doubt. We can only assume they made an accidental hash of getting Byrne back on the pitch after being treated for several minutes for a blood injury to his foot.
"When England transgressed in similar fashion in the 2003 Rugby World Cup, it was clear that they were so intent on never allowing themselves to get in the situation whereby they might be reduced to 14 men, no matter how briefly, that they over-stepped the mark, shoving wing Dan Luger on to the field against Samoa."
