The Egypt forward replaced Kevin Grobkreutz on 69 minutes when his side were maintaining a slender lead.

But Petar SliSkovic brought the score level one minute from time to end the match in a stalemate.

Dortmund's Mats Hummels netted the opener only after eight minutes.

Zidan, who plied his trade at Mainz from 2005 until 2007, couldn't make a notable impact in the game.

After shaking off a rib injury, he made his comeback against Hoffenheim a week ago in a league match that saw Dortmund's unbeaten run end.

Dortmund remain on top of the Bundesliga table with 62 points, ten clear of closest rivals Bayer Leverkusen.
