France and Arsenal defender Laurent Koscielny will miss the World Cup after suffering a torn Achilles on Thursday.
Less than 10 minutes into his club’s Europa League semi-final second leg at Atletico Madrid, the centre-back went down unchallenged after appearing to lose his footing on the Wanda Metropolitano turf.
His discomfort was plain to see, as he grimaced on the floor while clutching his Achilles tendon.
Arsenal officials instantly recognised that Koscielny would play no further part in the game, and prepared Calum Chambers for an early first substitution.
Koscielny received limited treatment on the pitch and was then stretchered off, with the game still poised at 1-1 on aggregate after Arsenal and Atletico played out a score draw in the first leg.
While Arsenal are yet to make an official statement, Goal can confirm that Koscielny has torn his Achilles tendon and faces a prolonged spell on the sidelines.
