Lazio missed the chance to draw level with Serie A leader Juventus as it was held to 2-2 at struggling Palermo on Saturday.
Sergio Floccari gave Lazio the lead in the 10th minute with a powerful looping header after a brilliant long ball from Cristian Ledesma.
Floccari had a second goal harshly ruled out for offside in the 64th.
The game turned on its head in the space of a minute in the second half as first Arevalo Rios evaded his marker to slot home Andrea Dossena's cross at the far post.
Moments later Fabrizio Miccoli touched on Josip Ilicic's cross for Paulo Dybala to slot home.
Lazio leveled from the spot after Ezequiel Munoz fouled Floccari. Hernanes fired into the bottom right corner, despite Palermo goalkeeper Samir Ujkani guessing the right way.
