Bath boss: Toulon match can't happen
The match, which was due to be played in the southern French town of Toulon on Saturday was one of five games that were meant to take place that weekend in France which were called off following a series of attacks across Paris which killed at least 129 people.
However, European Champions Cup ties where French clubs were the away team did go ahead, with Toulouse losing 32-7 at English Premiership side Saracens' Allianz Park ground in north London on Saturday.
Craig, a member of the European Professional Club Rugby (EPCR) board which runs the Champions Cup tournament, said the already congested nature of the English domestic season, caused by England staging this year's World Cup and the national side's tour of Australia at the end of the current campaign, made finding a gap in which to play the Bath-Toulon match impossible.
"It is very clear to me that the Toulon match can't happen," Craig, who is based in Aix-en-Provence, told Monday's edition of Britain's Daily Telegraph newspaper.
"The midweek option is not an option to my mind as that would to the detriment of player welfare as well as the integrity of two competitions, an important Champions Cup game being squeezed in with all the attendant travel issues between two (English) Premiership weekends.
"There is no way we should be letting that happen. You can't play three high-profile games in a week."
Craig added: "In the wider context of what has happened in Paris, this is not a serious matter, of course it isn't. And I do understand why the decision was taken.
"But from a rugby point of view, and from the point of view of the competition, this is an issue of significant consequence. There is no place to fit it in. It is a bit of a disaster in that regard.
"There are simply no free weekends available between now and the end of the season.
"It is unacceptable that the international calendar does not take into account the domestic game. We are playing matches right through the 2016 Six Nations championship to get everything fitted in. There are 33 weekends all accounted for and no slack.
"And why England are going off on a tour to Australia at the end of a World Cup season I don't know. What is the point? The players will be knackered.
"They are like lambs to the slaughter. They are just being destroyed. Have a tour before a World Cup but not after one."
Meanwhile EPCR chairman Simon Halliday said: "We will work through everything.
"This is going to be a consultative process with all those involved, and will not be a matter of us quoting the rule book and telling people to get on with it.
"It is an unprecedented situation and it is important we take into account all sensibilities," the former England international added.
