This has apparently already been discussed at the Prem meetings and has been reported by some journalists.
The 20 clubs have been told apparently that if you have 14 players - 11 to start and 3 subs out of the squad of 25 then that constitutes a team to start and therefore finish a game.
So that accounts for 11 in total out of a squad of 25.. Yes, it's tough shit on any team in that situation, but clubs have apparently been told/agreed to the principal of finishing the season by playing games.
It's therefore in the best interests of clubs to keep them healthy.
