Chelsea's transfer ban has been lifted, freeing up manager Frank Lampard to make signings in the January window.
The Court of Arbitration for Sport (CAS) has halved Chelsea's two-window FIFA transfer ban and their financial sanction, after the west London club's appeal.
The Blues were hit with the FIFA transfer embargo last season on issues relating to the signing of overseas youth players.
Chelsea will now be able to sign new recruits in January, with a left-back a priority for manager Lampard.
The Blues can also look at a replacement for Eden Hazard, who left for Real Madrid in the summer on a deal that could rise as high as £150million.
Swiss-based CAS confirmed it had "modified" FIFA's sanctions following Chelsea's appeal, halving the length of the transfer ban and also cutting the club's fine in two.
The CAS statement read: "The following sanctions have now been imposed by the CAS: Chelsea is banned from registering any new players, either nationally or internationally for one entire registration period, which the club already served during the 2019 summer registration period.
"Chelsea is ordered to pay a fine to FIFA of the amount of 300,000 Swiss Francs.
"The warning and the reprimand are confirmed."
