The Argentine - originally estimated to be out for as long as a month - apparently impressed manager Pep Guardiola with the quickness of his recovery.
"He has had his first training session and he did quite well," the Spaniard told reporters Friday, courtesy of BBC Sport. "Maybe he could be back for tomorrow."
Aguero suffered the injury in Amsterdam on his way back from a concert a fortnight ago. The taxi he was travelling in slammed into a lamp post - an incident which he said would've been far worse had he not been wearing a seat belt.
The 29-year-old missed the next three matches for club and country - including Argentina's final two World Cup qualifiers - but took part in light training earlier this week. He completed a full session with his teammates on Thursday.
The prospect of a healthy Aguero is sensational news for City supporters, who are waiting for him to break the club's all-time scoring record. He's just one goal shy of matching Eric Brook's 177-tally standard.
However, Guardiola had no significant update to share on skipper Vincent Kompany's status. The Belgian, who remains out with yet another calf injury, hasn't played since a 2-1 win over Bournemouth on Aug. 26.
