During the first half of the Monday night matchup between the Philadelphia 76ers and the Chicago Bulls in South Philly, the visitors lost a key starter. Lonzo Ball was seen leaving the court for the Bulls’ locker room during the second quarter of the matchup.

Ball injured his left knee Jan. 14, 2022, against the Warriors, and it seemed at first to be the kind of thing that would be fixed pretty fast. Originally diagnosed as a bone bruise, it soon was discovered he also had torn the meniscus in the knee.

Lonzo Ball will not return to Monday's game between the Chicago Bulls and the Philadelphia 76ers due to a head injury.
