After several meetings, representatives of the city merged Erciyesspor, Sanayispor, and Ortaanadoluspor to form Kayserispor.

Yener scored the first goal in club history when he netted a shot in the 17th minute against Ankara Toprakspor.

The club finished with a nine win, nine draw, and twelve loss record in 30 matches while scoring 21 goals and conceding 33.

Kayserispor defeated Galatasaray in the quarter-finals of the 1977–78 Türkiye Kupası, and reached the semi-finals for the first time.

However, prior to the start of the season the club withdrew itself from participating in the Turkish Regional Amateur League.

Minor disturbances and unrest were reported around the city and the Sivasspor fans were accused of acts of hooliganism and vandalism.

The match kicked off at 16:00 in front of 21,000 fans in the Kayseri Atatürk Stadium, the troubles started in the 20th minute when Kayserispor's Küçük Oktay scored.

Witnesses at the game reported that Sivasspor supporters responded by hurling rocks and stones at the Kayserispor stands.

Kayserispor fans retaliated by marching onto the Sivasspor supporters with stones, sticks and knives.

The outnumbered Sivas fans tried to flee however, the exit gate malfunctioned and wouldn't open, this caused a crush in which 41 people died and 300 were injured as a result of being stamped on and suffocated.
