A late own goal by Parma goalkeeper Simone Colombi sent Lazio to the Italian Cup quarterfinals with a 2-1 win on Thursday.
Lazio will next play Atalanta in Bergamo on Jan. 27.
The match appeared to be heading for extra time when, in the final minute, Vedat Muriqis header came off the base of the right post and went in off Colombi.
Muriqi hit the post in the first half too, as did Andreas Pereira, moments before Lazio eventually took the lead in the 23rd minute when Marco Parolo headed in Pereiras cross.
Parma could have leveled in the 72nd but Valentin Mihil fired off the crossbar from point-blank range.
Mihil did get the equalizer seven minutes from time when a through ball caught the Lazio defense napping and the Romanian beat goalkeeper Thomas
Strakosha one-on-one to lift the ball into the bottom right corner.
