The deputy Zambia captain returned to camp in Ndola on Monday after he was given four days compassionate leave following the death of his sister last Wednesday.
The defender from French Ligue 2 club Sochaux was part of training on Monday night at Levy Mwanawasa Stadium where Wednesday’s 2015 Africa Cup Group F qualifier against Niger will be played.
Team manager Lusekelo Kamwambi says the technical bench will assess the situation whether Sunzu will lead Chipolopolo in battle.
Should Sunzu not captain the team on compassionate grounds, the armband will go to the third skipper midfielder Nathan Sinkala.
Sinkala captained Zambia against Niger in the scoreless first leg on October 11 before handing over the armband to Katongo in the 78th minute when he came on for Chisamba Lungu.
Katongo was axed from the team just 24 hours after Zambia returned from Niger for what coach Honour Janza termed as in the interest of unity and team spirit
