Chicago Fire FC Signs Harold Osorio and Sam Williams to Short-Term Agreements

Chicago Fire FC News Release


CHICAGO - Chicago Fire FC today announced that the Club has signed Chicago Fire FC II midfielders Harold Osorio and Sam Williams to short-term agreements. Both Osorio and Williams will be available for today's Chicago Fire FC home opener against D.C. United at Soldier Field.

Kickoff against D.C. United is scheduled for at 7:30 p.m. CT. The match will be broadcast live on MLS Season Pass on Apple TV, and transmitted locally in English on WLS 890 AM and in Spanish on Que Buena 105.1 FM via the Uforia App.

Both Osorio and Williams traveled with the Fire for the Club's season opener against the Columbus Crew last Saturday. They took part in Chicago Fire's preseason camps, earning minutes against Brazilian First Division side Fortaleza and MLS Western Conference foe Sporting Kansas City in Florida and playing against LAFC, Portland Timbers and San Jose Earthquakes at the Coachella Valley Invitational. Both also played in a closed-door scrimmage against Las Vegas Lights FC to close out preseason.

Osorio, 21, joined Chicago Fire II, the MLS NEXT Pro side of the Club, in August 2022 from Alianza Fútbol Club in El Salvador's Primera División. The El Salvador international has since played in 33 matches across all competitions for Chicago Fire II, including the MLS NEXT Pro regular season, MLS NEXT Pro playoffs and the Lamar Hunt U.S. Open Cup. Osorio scored nine goals as a midfielder in 2024, second on the team behind league-leading goal scorer David Poreba (18 goals).

Williams, 19, joined Chicago Fire II in January 2025 from the University of North Carolina. Williams began his career with the New York Red Bulls Academy, where he became the first graduate to reach 2,000 minutes for New York Red Bulls II during the 2022 USL Championship regular season as a 17-year-old. At North Carolina, Williams was named to the 2022 All-ACC Freshman and All-ACC Academic Teams.

This is the second short-term agreement for both Osorio and Williams in 2025. Per MLS rules, a Club may sign a player from its affiliate (MLS NEXT Pro or USL) to a maximum of four Short-Term Agreements (up to four-day contracts) each season (maximum of 16 days). An individual player may be included on up to four MLS regular season match rosters each season. However, that player may appear in no more than two MLS regular season matches. An individual player may appear in any number of non-league games during the terms of his four Short-Term Agreements.
