Monday's 1-1 draw at Hellas Verona cost Lazio a chance to finish third in the Serie A standings.
When striker Pedro found enough space in the penalty area to turn and fire the ball into the top corner, Maurizio Sarri's team took the lead just before halftime.
However, Cyril Ngonge's goal from a set piece six minutes into the second half brought the hosts level.
Two minutes later, Verona could have completed their comeback, but Darko Lazovic's close-range shot hit the post.
At Marcantonio Bentegodi Stadium, both teams had chances to win, but the points were split.
With 39 points, Lazio is fourth in the league, one point behind AS Roma, who are third. 18th is Verona.
