The utility back, signed from Huddersfield Giants last month, has been listed in the Wales squad for a game on Sunday but Hugh said in today's Daily Record: "It is a complete mystery to me why Hefin's name was linked with the Welsh rugby league set-up. There is no way we'd consider releasing him as we have a Celtic League game at Llanelli this weekend."
Glasgow also have a Heineken Cup match against Leinster the day after Wales are due to play Ireland in Dublin.
