Zambia midfielder Nathan Sinkala has been sidelined for the remainder of the Africa Cup of Nations due to a knee injury.
The 24-year-old suffered the problem during his side's 1-1 draw with Congo on Sunday.
Sinkala, who won the tournament with his country in 2012, is expected to be out of action for around four weeks.
Zambia continue their Group B campaign on Thursday when they face Tunisia.
