Yesterday's newspapers carried reports that the hooker was to quit international rugby and move south to play in the Zurich Premiership.
The Scotland skipper said: "I have nothing to say on matters like that at the moment."
A number of senior players are thought to be ready to join prop Tom Smith who told colleagues he was retiring from the international scene after Saturday's defeat to England, although Smith would neither confirm or deny the claims yesterday. There are reports today that Nathan Hines is moving to French side Perpignan from Edinburgh, while Jon Petrie and Sean Lamont are thought to be leaving Glasgow.
The reports come as speculation over the future of Matt Williams continues with claims that relations between the coach and the players is non-existant. One senior player said: "The squad feel they have been treated like morons and robots.
"The coaching team is like a dictatorship with even the most seasoned players not being allowed to chip in with ideas or opinions.
"Under this regime, it seems individuals are not allowed to express themselves on or off the pitch and that is so frustrating.
"Some players actually know a bit about the game - whereas some of the coaches never played at international level.
"We are hellbent on winning for Scotland. But they want to do that as players and not as a collection of robots."
