The field is set.

Major League Soccer on Thursday unveiled the four rosters featuring all 72 players that will be showcased to MLS coaching staffs during the 2013 MLS Player Combine in Lauderhill, Fla.

All four teams are led by college coaches as well as a representative from the US club soccer scene as they get ready to face three doubleheaders that will be held between Jan. 11-15 at Central Broward Regional Park.

Of the 54 players previously invited back on Dec. 11, three have withdrew from the Combine. UCLA's Ryan Hollingshead will miss the event due to previously scheduled travel, Joe Franco of Cal State Northridge is recovering from knee surgery and Louisville's Paolo DelPiccolo declined the invitation.
