Cole Palmer is currently expected to be injured for approximately 4 to 6 weeks due to a groin injury. He had to withdraw from a match against West Ham due to the injury and underwent a scan that showed positive but cautious results. The injury is serious enough that it might keep him sidelined for this duration, though there is some hope he could return shortly after the upcoming international break, potentially missing the West London derby but possibly returning soon after. Chelsea is being cautious with his recovery given the risk of groin injuries becoming persistent problems if rushed back too soon.
In summary, the expected absence period for Cole Palmer is roughly 4-6 weeks from late August 2025.
