Analysts predict: Yockers will be injured for at least 2 weeks, and the specific time will depend on the severity of the injury.

Physio Scout, an account that focuses on player injuries, analyzed Yockers' injury. The article believes that Yockers is most likely to have a muscle strain.
In last weekend's league match, Yockers was replaced at halftime. According to the game video, his most likely injury was a hamstring strain in his right leg (the specific level is to be confirmed), which may also involve the adductor muscles. Arteta confirmed that Jokeres will definitely not be available for the Champions League match against Slavia Prague.
Estimated recovery time:
Grade 1: 2-4 weeks
Grade 2: 4-6 weeks
Grade 3: 8-12+ weeks (longer recovery time if tendon involved/requires surgery)
The final diagnosis and recovery timetable will be determined after imaging, and since Yockers has continued to play, the injury does not appear to be too serious, which may indicate that the injury is closer to a Grade 1 or 2.
