Timber, who recently joined the club from Ajax just last month, made his competitive debut during the 2-1 victory against Nottingham Forest on Saturday.
However, his appearance was cut short in the early stages of the second half, fueling speculation about a potential severe knee injury.
The confirmation has now come in, revealing the unfortunate truth.
The right-back, Timber, is set to undergo surgery for the injury, plunging him into a lengthy period of rehabilitation.
As a consequence, he is expected to be sidelined for several months, with the likelihood of missing the entirety of the 2023–24 season.
“Further to detailed assessments with consultant specialists since Saturday, we can confirm that Jurrien Timber has sustained an injury to his anterior cruciate ligament in his right knee,” said the club in an official statement. “Jurrien will undergo surgery in the coming days and will be out of action for a period of time.”
Writing on social media, the player said: “Gutted to share that my injury is more serious than expected, especially after the warm welcome I’ve received. I wanted to repay you on the pitch, which will not be possible for the forthcoming period.”
While the player will undoubtedly be eager to make a swift return to the field, it’s probable that his season has concluded prematurely. Arsenal’s priority will be to avoid hastening his comeback in order to prevent any potential setbacks or relapses.
