Arsenal defender Jurrien Timber to undergo ACL surgery, faces lengthy absence

Timber injured his ACL during his competitive debut for Arsenal against Nottingham Forest.
The exact length of Timber's absence is unknown, but ACL injuries typically require 6-12 months of recovery.
Timber's injury impacts Arsenal's defensive depth and they may look to sign reinforcements in January.
Manager Mikel Arteta has criticized the packed fixture schedule, which he believes is causing more injuries.
Other high-profile players like Kevin De Bruyne have also suffered ACL injuries early this season.
