Arsenal defender Hector Bellerin will miss the remainder of the season after it was revealed he ruptured his anterior cruciate ligament against Chelsea.
The Spain international was forced off on a stretcher in the 70th minute of the Gunners' 2-0 win on Saturday after falling awkwardly when challenging for the ball.
And the club has now confirmed that he faces between six and nine months on the sidelines, meaning he could also be ruled out of the start of the 2019-20 campaign.
"Further to the injury sustained during our match against Chelsea on Saturday, we can confirm that Hector has ruptured the anterior cruciate ligament of his left knee," a statement read.
