Chelsea will be able to sign players in January after the Court of Arbitation for Sport (CAS) reduced the club's transfer ban.
Chelsea were handed a two-window transfer ban and fined £460,000 ($599,000) in December 2018 after FIFA found them guilty of breaching rules relating to the transfers of 29 players under the age of 18.
The club were found to have breached Article 19 and Article 18b of the Regulation of Transfers and Status of Players by FIFA's Control, Ethics and Disciplinary Committee.
Friday's decision by CAS marked Chelsea's second appeal of the ban after FIFA rejected an earlier attempt to lift the ban and upheld their decision in May, but altered the ruling to allow the club to sign players younger than 16.
