Chelsea will learn the verdict in their appeal against a two-window transfer ban by mid-December, the PA news agency understands.
Lawyers for the Premier League club presented their case at the Court of Arbitration for Sport (CAS) on Wednesday, with the hearing understood to have finished at 2.30pm UK time.
The CAS panel is expected to announce its findings in the first or second week of December. The timing means that, depending on the outcome of the appeal, the club might be able to do business in the January transfer window.
FIFA found the London club guilty of breaching article 19 of its regulations on the status and transfer of players (RSTP), which concerns the protection of minors.
They were also found to have breached article 18, concerning third-party influence.
Chelsea appealed to FIFA and the case was heard in April, but documents published by FIFA at the end of October showed its appeals committee found the Blues had committed 150 breaches of regulations.
The appeals committee agreed with the disciplinary committee that the breaches were “inexcusable”.
