Real Madrid winger Angel Di Maria is out for two weeks with a leg muscle injury.
Di Maria limped out of Madrid's 2-1 victory over Manchester United in the UEFA Champions League on Tuesday night just before half-time and has undergone a series of tests since returning to the Spanish capital.
The team's doctors have diagnosed a sprained muscle in his left leg and have advised Di Mario not to play for at least a fortnight.
The Spanish club are reluctant to take any risks, as last season saw the former Benfica winger miss approximately 10 weeks with thigh and hamstring injuries.
Real Madrid face Celta Vigo on Sunday before playing Real Mallorca a week later.
