Sevilla FC midfielder Sebastián Cristóforo will be out for six months after he tore the anterior cruciate ligament in his left knee at the weekend.
Cristóforo sustained the injury in the closing minutes of his team's 4-1 Liga win against Real Valladolid CF on Sunday. After carrying out tests on the 20-year-old, club medics said the former CA Peñarol player would require surgery followed by a lengthy recovery period.
The news represents a further setback to Sevilla coach Unai Emery, who was already shorn of Daniel Carriço (ankle) for Thursday's UEFA Europa League second leg against Real Betis Balompié.
There are also doubts surrounding the fitness of Cameroon defender Stéphane Mbia, who pulled out of Monday's training session with a thigh complaint. Sevilla trail city rivals Betis 2-0 going into the return at the Estadio Benito Villamarín.
