Bologna had Aaron Hickey sent off after just 17 minutes and parked the bus to earn a 1-1 draw away to Sassuolo.
It was another Emilia-Romagna Derby, although Sassuolo missed Jeremie Boga, Filippo Romagna and Medhi Bourabia, while Bologna were without Federico Santander, Gary Medel and Paolo Faragò.
The visitors started very aggressively with three corners in the first three minutes, but Sassuolo were unable to make the most of a poor Adama Soumaoro back-pass.
Bologna’s intensity paid off, as Musa Barrow pounced on Francesco Magnanelli’s error, robbed Marlon inside the box and pulled back for Roberto Soriano to fire in from six yards. Sassuolo were trying to play out from the back, but were caught napping.
Filip Djuricic needed an excellent tackle to stop Nicola Sansone on a slalom, but VAR called the referee back to view a very late and high Aaron Hickey tackle on Mert Muldur. It was ruled to be reckless and rewarded with a straight red card for the Scottish teenager.
It turned rapidly into a Sassuolo siege on Lukasz Skorupski’s goal, with the game played largely inside the Bologna penalty area, but the shots were either charged down or off target, until Skorupski smothered the Manuel Locatelli effort on the stroke of half-time.
The equaliser arrived when Djuricic’s snapshot took a deflection off Lorenzo De Silvestri, turning into an accidental assist for Francesco Caputo, who immediately spun round to fire in from 10 yards.
Soumaoro bravely intercepted a Caputo roll across for substitute Hamed Junior Traore, who was ready to tap in from six yards, then Traore scuffed wide and Skorupski flew to palm away a looping Marlon header.
Berardi juggled with the ball on the edge of the area before drilling wide with Skorupski stranded, and the goalkeeper smothered another header, but a combination of Bologna parking the bus for an hour and Sassuolo being too complicated with their approaches saw it end 1-1.
