The Pilgrims, who are currently touring Sweden, have slammed reports claiming that a deal is close for the Wales Under 21 international defender.
"The club very rarely comments on speculation," Argyle director Damon Lenszner told his clubs official website.
"It is unsettling for the team and the player to hear speculation like that.
"There was an offer which was rejected, he is an Argyle player and we want him to remain an Argyle player.
"He is a promising under 21 international and part of the set up here and he has 12 months left on his contract.
