Nick went to collect a high ball and collided with Wasps Scrum Half Joe Simpson, who was yellow carded for his part in the collision.
Nick said earlier today, "I am feeling fine, it was just one of those things. Joe is a great lad who meant no harm at all. He came to me as I left the field to see if I was okay and we had a chat about it after the game.
"I must say, though there is something about Wasps that is strange. Last year I hurt my back, this season at the AJ Bell Stadium I injured my elbow now this! Hopefully I can get through a full game against them next season.
"We have got a few days off now and I am looking forward to starting preparation for the Northampton game."
