Real Madrid have confirmed that right-back Alexander-Arnold sustained a muscle injury during their 2-1 victory over Olympique Marseille in the UEFA Champions League group stage on Tuesday night at the Santiago Bernabéu.
The England international was forced off after just three minutes of play, with Dani Carvajal coming on as his replacement.
In an official statement released on Wednesday, the club announced that medical tests revealed a hamstring injury in the player’s left leg.
However, the statement did not specify the exact duration of his absence.
Spanish outlet Cadena COPE reported that Arnold is expected to be sidelined for six to eight weeks.
This projected recovery time means he could miss up to ten matches across domestic and European competitions.
Among the fixtures in doubt are crucial league encounters against Espanyol, Levante, Atlético Madrid, Villarreal, Getafe, and Barcelona, as well as Champions League clashes with Kairat Almaty, Juventus, and Liverpool.
Doubts remain over his availability for the highly anticipated El Clásico against Barcelona and the Champions League showdown with his former club Liverpool, making his absence a significant blow to Carlo Ancelotti’s plans for the coming weeks.
