Lazio and Roma remain in joint third place after an ill-tempered draw, which saw the Giallorossi hit the woodwork twice and Stefan Radu sent off.
Bruno Peres saw his angled drive come off the inside of the far post and in stoppages Dzeko had three chances in the space of a minute, one denied by Thomas Strakosha, another off the crossbar and a third flashing wide.
Radu saw red for a second bookable offence, the 10th dismissal in the last 10 editions of this fixture, but Lazio held on and even had scoring opportunities when down to 10 men.
