Scotland front-row Zander Ferguson has criticised proposals for the Six Nations to be played over five consecutive weekends.
England's top clubs have submitted plans for the tournament's six countries to play their five Tests without a break.
The idea has received plenty of criticism already with increased costs for fans and player welfare amongst the main concerns.
Ferguson, who is keen to play for his club Glasgow against Ulster this weekend, echoed those sentiments. He feels playing Test rugby consecutively for several weeks would take its toll on players.
"I think that's completely implausible," the 21-year-old told Press Association Sport when questioned about the suggested changes which, if approved, will be implemented from 2020.
"I feel sorry for the guys who might have to play for their clubs this weekend. We get looked after pretty well so unless it's a necessity I don't think a lot of the boys will be playing.
"I don't know if I'll have the weekend off. I'm not the boss. If I have to play for Glasgow I'll play for Glasgow. I like my rugby and want to play every game.
"Having been in the junior World Cup, where you play five games over four weeks, it is pretty brutal, and that's at Under-20 level. Internationally it would be ridiculous. I don't think that could ever happen."
