FC Barcelona’s injury woes have worsened with defender Andreas Christensen suffering a ligament sprain in his ankle in Tuesday’s 1-0 UEFA Champions League defeat to Inter Milan.

Christensen was substituted in the match’s 58th minute after struggling for a few minutes with the issue, and FC Barcelona has since confirmed the left ankle injury.

The club said further tests would be carried out on Wednesday to ascertain the full extent of the injury.

Christensen’s injury comes ahead of tough games, taking on Celta Vigo in La Liga this weekend, before the reverse fixture with Inter Milan on Oct. 12 and the Clasico against Real Madrid on Oct. 16.

The Blaugrana take on Villarreal and Athletic Bilbao in La Liga after that.

The ex-Chelsea defender was replaced by veteran Gerard Pique, who will likely come into starting calculations.

Christensen has started three La Liga matches and all three of FC Barcelona’s UEFA Champions League matches this term.

The 26-year-old Denmark international joins Frenkie de Jong, Memphis Depay, Hector Bellerin, Jules Kounde, and Ronald Araujo on the sidelines at Camp Nou due to injury.
