Arsenal have been dealt a major injury blow by Kieran Tierney.

The London Evening Standard says Arsenal are set to be without left-back Kieran Tierney for three months after the club confirmed he dislocated his shoulder in Monday's 3-1 win at West Ham.

Tierney left the London Stadium with his right arm in a sling and was taken to hospital after he was forced off in the first half following a tussle with Michail Antonio.

The Scotland international faces surgery and could be sidelined until March.

The 22-year-old has made just 11 appearances this season and will now miss a large chunk of the remainder of the season.
