The Major League Soccer Player Association announced that it voted to approve its latest counteroffer to MLS as it relates to economic concessions for the 2020 season, modifications to the recently agreed upon CBA, and their agreement to participate in a summer tournament in Orlando.

But according to multiple sources, MLS has already pushed back, insisting that it has submitted its best offer and that it won't budge further. ESPN television analyst Herculez Gomez tweeted that MLS is giving the players until noon on Tuesday, otherwise they will lock the players out.

One source called MLS's threat "a disingenuous act," especially given how much the MLSPA membership has offered.

MLS has been shut down since March 12 due to the COVID-19 pandemic, and has been engaged in negotiations with the MLSPA over the past several weeks in a bid to soften the pandemic's economic impact.

In a statement, the MLSPA said their proposal includes salary reductions across the entire player pool, reduced team and individual bonuses, and additional concessions to existing and future terms of the CBA. The MLSPA is also requesting that the current CBA -- the framework of which was agreed upon last February but not ratified by either side -- be extended by one year to 2025.

If the deal is approved by MLS, the one-year CBA extension would push the total amount of concessions the MLSPA is making well beyond the $100 million contained in the union's previous proposal last Friday.
