Kubo, who missed more than a month due to a left‑leg hamstring tear sustained against Barcelona, has begun ball work under the watchful eye of the recovery team. His progress from gym to continuous running and back to the ball marks the start of the final rehabilitation phase.
Real Sociedad’s coaching staff are cautiously optimistic, aiming to have him ready for the second leg of the Copa del Rey semi‑final against Athletic Club on March 4. A successful return would give the Basque side a key weapon to secure a place in the final.
