Arsenal confirmed on Monday evening that further assessments will be needed to determined a timeframe for Timber’s return to action.

“Further to his substitution during our match against Nottingham Forest on Saturday, Jurrien Timber has received extensive assessments and scans which have confirmed he has sustained an injury to his right knee,” a club statement read.

“Jurrien will undergo a further detailed assessment and review with a consultant in the coming days to assess the full extent of the injury, in order to determine the next steps. A further update will be provided in due course.

“Everyone at the club will be focused on supporting Jurrien at this time.”
