Only 22 players have reached that mark before, former team mate Alex Brown being one of them, and one wonders how many Premiership games he would played had he not missed so many while on international duty?
Tins is still going strong as he proved with his fine performance against Leicester Tigers at Welford Road last weekend, and Nigel Davies spoke warmly of the centre's achievements today.
"It's an amazing achievement, it really is. The fact of the matter is that he's not just making his 200th appearance, he's actually playing very well at the moment. He was outstanding last weekend up at Leicester.
"His influence on the team is very important because they are a young group. We're trying to develop leadership within the group, but there aren't a lot of natural leaders there.
"Someone like Mike adds a lot of value to the team, a lot of the stuff that you don't see in terms of the way he energises and drives the group.
"His own individual performance was very good at the weekend and, if he can maintain those standards, at the age he is going into his 200th appearance, it says a lot about the character of the man."
