Serie A - Round-up: Lazio struggle to draw
Lazio missed the chance to close the gap on Serie A leaders AC Milan to a single point as they were held to a 1-1 draw with Catania.
For all their possession Lazio could not break down a stubborn Catania rear-guard defence and they had to come back from a goal down to grab a point.
The visitors took a surprise lead after 43 minutes. Cristian Llama's corner from the right was powered home by Matias Silvestre from six yards out to put Catania ahead.
But within 90 seconds Lazio had hauled themselves level.
Hernanes had the freedom of the Stadio Olimpico and charged forward. With no challenge forthcoming the midfielder shot from 20 yards and buried his effort into the bottom left-hand corner.
Chances were few and far between in the second period as Catania set out to frustrate their lofty opponents.
Mauro Zarate went closest for Lazio when he danced around five defenders only to see his delightful chip palmed away by Mariano Andujar in the Catania goal.
The result leaves Lazio in second place behind AC Milan while Catania remain in mid-table.
Bari stayed bottom after 14 games following a 1-1 draw with promoted Cesena, while Cagliari beat struggling Lecce 3-2.
Bologna, awaiting a possible points deduction for financial irregularities, tried to get their game with Chievo played but heavy snowfall meant the match was postponed just before kickoff.
Snow also hit Brescia but their 0-0 draw with Genoa went ahead after a short stoppage to paint the lines red.
In the day's early game, midfielder Dejan Stankovic set alight a freezing San Siro with his first three goals of the Serie A season in Internazionale's remarkable 5-2 win over Parma, their first league victory in a month.
