Christian Pulisic handed Chelsea a timely boost by making a return to training on Thursday.
Pulisic has spent the longest time in the treatment room after suffering an ankle problem while on international duty with the United States in September.
However, the Daily Mail says that the 23-year-old was able to make an appearance in training on Thursday.
While an immediate return to the first-team squad appears unlikely, Pulisic may target an outing when Chelsea face Malmo in the Champions League next week.
The winger has not featured for Chelsea since scoring against Crystal Palace on the opening day of the season.
