Cristoforo out for six months
Sevilla midfielder Sebastian Cristoforo is set to be sidelined until next season after suffering a serious knee injury.
The 20-year-old Uruguayan, who joined Sevilla from Penarol last summer, damaged his left knee in Sunday's 4-1 Primera Division win over Real Valladolid and tests on Monday confirmed he had torn the anterior cruciate ligament.
A Sevilla statement read: "The estimated period he will be out is six months after he undergoes his operation, the date of which has yet to be determined."
Sevilla's win over Valladolid was their fourth on the trot in La Liga and left them in seventh place, seven points off the Champions League spots.
Unai Emery's men are also still involved in the Europa League, where they will need to overcome a 2-0 deficit away to arch-rivals Real Betis on Thursday if they are to reach the quarter-finals.
