Major League Soccer will lock out referees after its union rejected a tentative contract, putting Lionel Messi’s Inter Miami on track to open the season next week with replacement officials. The Professional Soccer Referees Association said Saturday that 95.8% voted against a tentative agreement with the Professional Referee Organization, which supplies match officials to MLS, the NWSL and some lower-tier leagues. The PSRA said in a statement the tentative agreement lacked a sufficient economic package and quality-of-life improvements.
