One odd thing about the France v Wales 100 minute game : after the clock reached 80 minutes from then on it didn't stop for anything - for instance all through the prolonged discussions WB had with the 4th official the clock ran and ran. Same for subsequent injuries, same for the TMO inspection of a possible bite ... the clock just kept going.
This had a big impact : because the Welsh had a player in the bin. He was allowed back on to the pitch after ten elapsed minutes, which was MUCH less that than ten mins playing time.
Is there any justification in Law for that - or was is a complete cock up by the timekeeper. Who had one job
