Kieran Tierney’s shoulder injury is to be assessed by Arsenal today.
The left-back was clearly in a lot of pain as he walked jadedly off the pitch at West Ham on Monday night.
Gunners guru David Ornstein reported in The Athletic that Tierney has been nursing a shoulder problem in recent weeks.
The north Londoners had already lost Hector Bellerin to injury in the warm-up, before Tierney was forced off after 29 minutes following a collision with Michail Antonio.
Arsenal came from behind to end their nine-match winless streak as Freddie Ljungberg enjoyed his first victory as interim manager at the expense of his former club West Ham.
