Squad depth is set to be a deciding factor this weekend as French clubs face their third round of fixtures in eight days on Sunday.
If the Ligue Nationale de Rugby's own recommendation that no player should be involved in thee consecutive games were to be followed to the letter, then around 120 player be sidelined for Sunday's action. Its a ridiculous situation.
The early log-jam is not something new, Top 14 organiser having to squeeze in 29 rounds (including the play-offs), nine European Cup weekends and 11 international Tests in their calendar year.
The LNR has to organise those playing weekends in tandem with respect for players' holidays and a pre-season window.
To make matters worse for clubs, any player having been on the paddock for more than 80 minutes in the first two matches, last weekend and Wednesday, "should not play in the third game" on Sunday, the LNR has advised.
"It's a recommendation which we started to mull over in February," said Bernard Dusfour, head of the LNR's medical committee.
"It's the fruit of long discussions betweeen experts, that's to say, doctors and trainers but also coaches."
Dusfour said that proper "biological rehabilitation" started 72 hours after a match, and a string of games close together risked increased levels of fatigue and with that injury.
Needless to say, coaches have not been left overly impressed.
Racing-Metro coach Laurent Travers said it was "impossible" to play three games in so little time, stressing that rugby was a traumatic contact sport which also demanded a "mental freshness".
"If you don't pay for it immediately, it will come back later to haunt you," added Stade Francais backs coach Jean-Frederic Dubois.
Players' union president Serge Simon promised "more radical" action should there be an overwhlemingly negative outcome to playing games so close together.
"But I firstly see the positive side: it's the first time that we're trying to fix a rule and there's a real debate about the health of players," Simon said.
With a maximum of 35 players contracted to each club in the Top 14, there are some outfits that will undoubtedly suffer more than, say, Toulouse, Clermont or Toulon, big-spending clubs with large budgets.
Toulouse's trip to Montpellier headlines Round Five while two games in the capital will also gather attention as Racing Metro host Perpignan while Clermont visit Stade FranÃ§ais.
The top four clubs are all on the road as Toulon visit Biarritz.
