What happened: The midfielder damaged the external meniscus in his right knee during Sunday's 1-1 draw with AC Milan. Juventus said the procedure in Lyon was successful.
Why it matters: The captain's absence deepens a Juventus injury list that has reached nine. The setback removes a central midfield option for much of the campaign.
By the numbers: The reported recovery window rose from an earlier estimate of three months to five or six months.
What to watch: Juventus' next updates will focus on Locatelli's rehabilitation and return timetable.
