Sport says in order for Barcelona to sign a replacement, there are certain steps the club must first take.
One of those is presenting a formal petition to LaLiga, alongside the medical report which confirms the player will be out for at least five months. This Thursday, Barça have officially presented their case to the governing body.
The club have all the documentation required and have sent it to LaLiga. The league now have 72 hours to make a ruling.
If they rule in Barça's favour, the club will have 15 days to sign a replacement.
