Serge Gnabry completed the full training on Thursday before Bayern Munich's clash with Hertha Berlin.
The champions go to the capital on Sunday for their first game in the second half of Germany's domestic season.
Gnabry was forced to lose part of the mid-season training camp in Doha due to problems with the Achilles tendon, which he sustained earlier this month.
However, Bayern confirmed on their website that the 24-year-old completed the full 90 minutes of training on Thursday, including a match.
The news comes a day after top scorer Robert Lewandowksi returned to team training, the striker underwent surgery following a 2-0 win over Wolfsburg on December 21.
Gnabry has scored six times in the Bundesliga this season and scored six more goals. Only Thomas Muller (11) gave more league assists to Bayern during this period.
Hansi Flick's side face Hertha, knowing they could be seven points off the table if leaders RB Leipzig beat Union Berlin on Saturday.
