Celtic will reportedly play their European qualifiers at Murrayfield next season, should they qualify.
Celtic Park is due to host the opening ceremony of the Commonwealth games in July, so the club have instead eyed up the home of the Scottish national rugby side, according to BBC Scotland.
UEFA rules state that matches involving teams competing in the Champions League or Europa League must be played "either at the ground of the home club or at another ground in the same or another city within the territory of its association."
Hearts have previously played European home ties at Murrayfield, as their own Tyncecastle pitch was deemed too small.
