Ansu Fati could need a third operation for his knee injury.
The Barcelona winger has encountered another barrier in his rehabilitation from the injury, which could potentially end his season.
The latest surgery had already delayed his recovery.
However, according to Catalunya Radio, this second operation did not resolve the issue.
It too proved to be more difficult than doctors had expected, and his knee has yet to recover.
Fati picked up a knee infection in March, which obviously complicated matters.
This forced the teenager to postpone a decision on a new operation, which he has still not officially made.
His initial return date was set for March 10, but it was later moved back to late April.
Even now though, he is nowhere near able to even consider a return to action.
So, there are legitimate concerns that Fati will not be seen until next season.
