Odegaard made history last week as he became the first player in Premier League history to be substituted in the first half of three consecutive starts as he suffered an early knee issue.
Arsenal did not specify how long the knock is expected to keep Odegaard out of action but after he pulled out of the Norway squad this week for their upcoming matches against Israel and New Zealand as he club are try to protect him.
Former Norwegian national team doctor Lars Engebretse has given an update on the playmaker, who could be out for a number of months. He told Dagbladet:
“I don't have information about exactly what the MRI showed but based on the injury video, it could be a lateral ligament injury.
“If it is such an injury, Odegaard risks being out for six to eight weeks but it depends on the size.
“It could also be a more extensive injury, cruciate ligaments maybe. In that case, the period on the sidelines could be longer.”
The Gunners next take a short trip to Fulham on October 18th before facing the likes of Atletico Madrid, Crystal Palace, Brighton and Burnley.
Arsenal sit one point clear of Liverpool at the top of the table, but the loss of Odegaard could seriously hurt their title chances heading into what are some tough games.
