UPDATE: The original list of MLS players eligible for free agency this offseason was published on Monday, December 7. On Tuesday, December 8, Khari Stephenson, who was with the San Jose Earthquakes in 2015, was added to the list.

Major League Soccer announced its first-ever class of free agents on Monday eligible to negotiate new contracts with any of the league’s 20 clubs beginning on Tuesday afternoon.

According to the Collective Bargaining Agreement agreed to earlier this year, players who were either out of contract or didn’t have their option picked up following the 2015 season and are at least 28 years old and have a minimum of eight years of service in MLS are eligible for free agency.

Clubs were allowed to start negotiating with free agents at 1 pm ET on Tuesday, Dec. 8. No team may acquire more than two out-of-contract players via free agency in a given year.
