Despite his 72-minute appearance last season, ATK have retained the Portuguese World Cupper, and this season also, there's not much to write home about the marquee recruit.
He has managed to stretch his appearance to two matches and 99 minutes this season before being ruled out because of a rib injury in their 1-0 win over Kerala Blasters in Kochi.
"Postiga is still not in his best... We are waiting for him to recover as soon as possible," head coach Jose Molina said at the pre-match press conference.
In Postiga's absence, Iain Hume had stepped up brilliantly to become second highest scorer last season with 11 goals but the the Scottish-born Canadian is yet to find his rhythm with one goal from three outings.

There are more injury worries for ATK with centre back Tiri also not certain to play along with their Botswana midfielder Ofentse Nato.
"Tiri has a problem on his muscle and still not sure whether he would play tomorrow," Molina said about Tiri who sustained a muscle strain in the last game versus Mumbai.
ATK (five points) have a solitary win from three matches but have maintained an unbeaten record and Molina insisted they cannot afford to slip up at this juncture.
"I am sure it will be an tough match. We need to win tomorrow. All of us will give our best, we have to keep on improving," Molina said.
Last year's finalists FC Goa, on the other hand, have suffered three successive losses and they would be hungry for a win. Zico's team have scored one goal and conceded six goals and the astute Brazilian is in dire need of a goal scorer. They must now turn to Reinaldo da Cruz Oliveira their top-scorer from last season.
Four of them were draws, including two legs of the 2014 semi-finals, which Kolkata won on penalties. The other two matches were won by Atletico de Kolkata, including a 4-0 in their last meeting in Kolkata.
