Press Association The 21-year-old Denmark international was signed in the summer for a fee in the region of £4million and now faces a long road back. Okore limped from the pitch after half an hour of Villa’s 2-1 defeat by Newcastle on Saturday and was sent for an MRI scan. Manager Paul Lambert feared the worst for his new centre-back and that news was confirmed on Monday evening. A club statement read: “Following clinical examination and the results of an MRI scan, the club can confirm that Jores Okore sustained a ruptured anterior cruciate ligament injury in his right knee in the game against Newcastle on Saturday. “Jores will undergo surgery in due course and he could be sidelined for a period of up to nine months.” Okore’s injury occurred during an apparently innocuous collision with Newcastle striker Loic Remy. Aston Villa defender Jores Okore is out for up to nine months after rupturing the anterior cruciate ligament in his right knee.
