Mostert will undergo surgery Tuesday to address chipped cartilage in his left knee, David Lombardi of The Athletic reports.
Mostert announced Sept. 14 that he would require a season-ending knee procedure, but he had to wait around a month for doctors to find the correct donor components needed for the operation. Assuming the surgery goes as planned, Mostert is expected to be back to full health ahead of the 2022 season. The 29-year-old running back is set to become a free agent this spring.
