In the commentary they say that it must have happened after Varley got up.
According to Penney in the Indo today:
Varley has got 4 YCs up to now, so his record is decent enough."I haven't seen it, so I can't comment. Damien has got a pretty good record in that area. He said he got his foot caught up in the tackle, so we'll just have to wait and see the footage of it," said Penney.
