The Premier League won't be considering reducing the length of each half to less than 45 minutes.
PFA chief executive Gordon Taylor suggested the idea to limit the fatigue on players as the top flight plays catch up following the coronavirus pandemic.
However, the Premier League won't implement the change for the final 92 games.
Taylor told BBC Radio 4's Today programme: "We don’t know the future but we do know what propositions have been put, what ideas have been put [forward].
"The possibility of having more substitutes, games possibly not being the full 45 minutes each way with talks of neutral stadiums.
"There’s lots of things being put forward - try and wait and see what the proposals are.
"And then have the courtesy to let he managers and coaches and players assimilate all those and come to a considered view."
When asked about the chances of games being shorter than 90 minutes, Taylor said: "All I’m saying, there’s a lot of possibilities."
Taylor's comments are believed to have surprised Premier League officials, with The Telegraph claiming that no conversations around shortened games have taken place.
