Yes, I recall that of Tom David. He had a very good game IIRC. Wasn't Gerald Davies also injured, hence John Bevan getting a place?
Watching the move again that led to the Edwards try, it started with a lineout throw from Pullin. I hadn't noticed before, but JPR Williams was involved in that passage of play twice, and both times he was tackled was at neck height in a manner that I reckon would probably stand a good chance of a yellow card these days.
