Major League Soccer has made a formal proposal to the MLS Players Association regarding salary reductions due to the coronavirus pandemic, with the league now seeking a 20 percent pay cut across the board, sources told ESPN.

The league is also asking the MLSPA to accept additional financial reductions apart from salary cuts that could run into the tens of millions of dollars, according to one source. The sources didn't elaborate on how the league would achieve those savings.

"MLS continues to engage in productive conversations with the MLSPA over ways in which we can collectively address challenges presented by the COVID-19 pandemic," said MLS president and deputy commissioner Mark Abbott.

The MLSPA did not immediately respond to a request for comment.
