Sadiq Umar today underwent surgery after he ruptured his ACL, his La Liga club announced.
Real Sociedad said the surgery was successful without any issues and he will be discharged by the weekend.
The 25-year-old striker suffered the major injury in a league game against Getafe.
This was just after he had completed a 26 Million Euros transfer from another La Liga club, UD Almeria.
He will miss the rest of the season on account of this injury.
