Kieran Tierney has taken to social media to reveal he had a successful operation after dislocating his shoulder against West Ham.

Arsenal’s summer signing lasted just under 30 minutes after he fell awkwardly and left the pitch with his arm in a makeshift sling.

Tierney, who has struggled for fitness this season with a hamstring issue, went down under no contact following a Hammers attack.

The Scotland international, who faces three months out, was making his first start under Freddie Ljungberg having struggled with a secret shoulder injury.

And after going under the knife, the ex-Celtic left-back posted an update from his hospital bed on his Instagram story to his followers.

He wrote: “Op done. Soup terrible. Thank you as always for the lovely messages. Helping me a lot.”

Tierney has a history of a troublesome shoulder that stemmed during his time at Celtic.

He was forced to have surgery on the same shoulder in 2017 after being forced to play through the pain barrier.
