The Egypt frontman came off the bench in the 58th minute to seal the win for Steve Bruce's men.

Senegalese forward Henri Camara fed Zaki inside the six-yard box and the 25-year-old pounced to score in stoppage time.

Earlier in the game, Sheffield Wednesday came from behind twice before Zaki settled the contest.

Wigan led through a goal from veteran striker Emile Heskey in the 17th minute but Jermaine Johnson leveled the score two minutes later.

Titus Bramble restored Wigan's advantage in the 37th minute before Deon Burton equalized once again ten minutes after the break.

Zaki, who joined Wigan on a season-long loan from Zamalek, is hoping to take part in his side's Premier League opener against West Ham United on August 16th.
