In their latest outing at the negotiation table, MLS and the Professional Referees Organization (PRO) did not come to terms with the Professional Soccer Referees Association (PSRA), over a new Collective Bargaining Agreement (CBA).

PRO, who assign referees across the USA and Canada for MLS matches, locked out the league's referees on February 18. Since, the PSRA have been protesting outside MLS and PRO offices in New York City, while sharing details on social media of what they are asking for in their new CBA - and why MLS and PRO are opting to not agree with them.

The Athletic reported Wednesday that it had obtained a copy of an update on negotiations that was sent to it's members via email.

It read: "In joint session, PRO representatives made a long statement criticizing, among other things, your negotiating committee’s decision to send (the first tentative agreement) through ratification to allow you to vote and have your voice heard on (it.) PRO then stated they needed yet more time to consider PSRA’s proposal and would not be providing a counter-proposal during the session.”
