Leeds United are set to take on Port Vale in the League Cup on Wednesday.
Doukara was left out of Leeds match day squad for the first day of the season against Bolton Wanderers.
And with so many players ahead of him in the pecking order at Elland Road, it may already be make-or-break time for Doukara.

Leeds have brought in the likes of Ezgjan Alioski, Caleb Ekuban and Hadi Sacko this summer.
And Doukara now seems to face a massive task to convince Thomas Christiansen that he still has a future at Elland Road.
Doukara has never been a consistent starter for Leeds, but he did show his worth at times last term.
But Christiansen appears to have his reservations about the Senegalese forward, and it may be that a poor performance against Port Vale could spell the end for Doukara at Leeds.
