The early minutes of the second half saw a real scramble in the Fenerbahce area.
Sivasspor's Sefa Yilmaz ran through Fenerbahce defense after a long ball, however Berke Ozer rushed to leave his goal as he cleared it. Olarenwaju Kayode took the control of the ball to attack, but Ozer was not still in his goal.
Some Fenerbahce players rushed to contain Kayode, but the Nigerian forward made a low shot that was saved by Ozer. Soon after Sivasspor's Malian forward Mustapha Yatabare controlled the ball on loose to lob the ball at the far post. Fenerbahce defender Nazim Sangare was at the right place and headed the ball to corner.
In the minute 73, Sivasspor's Yatabare unleashed a volley to hit the bar.
A minute later Sivasspor leveled the match as the home team's Brazilian winger Pedro Henrique scored a stunning long-range free kick.
The ball hit the underside of the crossbar and then went inside.
