personally l do not think so as the ball could not be seen...

l agree.how can they give a try when they couldnt see if the ball touched the ground!!!!!

my hubby reckons it should - l missed it so have no idea

yes.
It was across the line and not dropped so the presumption must be a try if it cannot be seen in that situation

When a try goes to the TMO, the words of the ref have a lot to do with the TMO is decision!

In this case, the asked ''is there any reason not to award a try''
as the replayed showed, the ball could not be seen, therefore there was no DECISIVE (key word) reason why the try could not be giving!

In the England v Wales game the ref asked the TMO
''try or no try''
the TMO said ''no try''.

It is all down to the wording of the ref!

Yes. There were no Irish players under the player with the ball so there was nothing to prevent the touch down.
