AC Milan can confirm that Kyle Walker sustained a fracture in his right elbow. To ensure better healing and optimise recovery time, the player underwent surgery in Milan to repair the olecranon through osteosynthesis. The operation went perfectly to plan. Kyle will begin rehabilitation immediately, as per the club's official statement.

Walker injury: What is the recovery timeline?
The decision to intervene immediately was made in an effort to reduce recovery time as much as possible. The severity of the fracture and the urgency of the operation made it necessary to act quickly to minimize time on the sidelines. According to the latest reports, Walker is expected to be out for only a few weeks, with hopes that he can return in under a month, thereby avoiding a premature end to his season, as relayed via Milannews.it.
Who will replace Kyle Walker at AC Milan?
With Kyle Walker out for the next few weeks and Emerson Royal still sidelined, Sergio Conceição will likely be forced to deprive Milan Futuro of Alex Jimenez’s presence. There is also the possibility of Alessandro Florenzi returning to the starting lineup, as he has fully recovered from the knee injury he sustained during the summer tour in the U.S. Filippo Terracciano could also be deployed in that position, but the former Verona player currently seems to be a peripheral choice in Conceição’s mind, who might opt to start Jimenez instead.
The issue suffered by Walker will rule him out not only for the match against Udinese, but also for the one against Atalanta on Easter evening and the return leg of the Coppa Italia semifinal derby. It is expected that he could return in early May.
