The Brazilian has been sidelined since July 16 because of an irregular heartbeat but the club have confirmed that the full-back is available for Sunday's Liga trip to Villarreal
The cardiac condiation was detected on July 16 and resulted in the versatile full-back sitting out his club's entire pre-season programme, as well as last weekend's Liga opener against Elche.
However, Adriano is now in contention to make his comeback in Sunday's meeting with Villarreal at El Madrigal.
"The Brazilian received the medical all-clear after training this Wednesday morning," read a statement on Barca's official website.
Adriano's return to full training comes less than 24 hours after the Catalans confirmed the imminent arrival of another Brazilian full-back at Camp Nou, with Sao Paulo's Douglas is set to seal a €5.5 million move to Barcelona later in the week.
