A group of Wales rugby stars have teamed up for a video message calling on people to back more law-making power for the Welsh assembly.
Shane Williams, Mike Phillips, Alun Wyn Jones and forwards coach Robin McBryde are supporting the Yes campaign in the referendum on 3 March.
The Yes for Wales campaign is led by Welsh Rugby Union chief executive Roger Lewis.
A leading No campaigner said politics and sport should be kept separate.
Nigel Dix of True Wales, which wants a No vote, said he would not tell the players how to play rugby.
The 70-second video had received more than 1,500 views on YouTube by Monday morning.
Williams says in it: "I want to see an assembly that's equipped to do the job. I think that laws affecting Wales should be made in Wales."
McBryde adds: "Rugby is a game of strength, speed and quick decisions, and we need quick decisions in our everyday life.
"A Yes vote will deliver more efficient law-making for Wales."
