That was his last appearance for Edinburgh this season, and came just as Denton felt he was rediscovering his best form, but after being named in the squad that will take on the Springboks, Samoa and possibly Italy in a quadrangular tournament, he is determined to make his mark.
He told the Scotsman: "It's been a very frustrating season for me.
"It started with a drop in form, I'm willing to admit that. I think I put a bit too much pressure on myself but then the annoying thing for me was that injury stopped me from getting back to my best.
"It was not until the Scarlets game [on 1 March], when I tore my knee ligaments, that I felt back to my true self and felt I was playing good rugby, which was part of the reason why I didn't want to come off the pitch after injuring myself.
"I finally felt that I had put together a performance that would get me back my starting position in the Six Nations. It is very frustrating but that is the nature of the game and, so long as I come out of this injury a better player than before, then I haven't lost the entire season."
