The 19 year old slipped and fell awkwardly in the final few minutes of the game and was stretchered off in obvious discomfort. It’s a blow for the young Irishman who was beginning to feature in and around the first team squad last season.
On his Twitter account he confirmed the injury, saying “I have damaged my ACL and lateral meniscus and will miss rest of season.I’m absolutely devastated but am determined to come back stronger!”
Meanwhile, there are fears over Theo Walcott’s ankle injury with Arsene Wenger saying it needs further examination.
Theo went home early and was due to have an MRI on Tuesday,” he told Arsenal.com. “It is an old ankle injury from the end of last season. It’s one that comes and goes.
“We need some more investigation because sometimes he’s completely free of it and sometimes it affects him. But we had to send him back because he couldn’t practice anymore.”
Walcott is likely to miss this weekend’s Emirates Cup and will miss the chance to face his ‘mentor’, Thierry Henry, who returns to the Emirates with current club New York Red Bulls.
