The Rome-based club, which started the match two points behind Juventus in fifth place, fell behind in the 23rd minute when Florian Thauvin broke through Lazio’s defense and volleyed home from close range following a scramble in the penalty area.
Lazio equalized just 10 minutes later through Alessio Romagnoli. The veteran defender scored his first goal of the season by poking in a corner kick from the right, which was initially headed on by Matías Vecino.
The draw extended both teams’ unbeaten runs in the league to six games, but Lazio remained in fifth place, one point behind Juventus, who suffered a heavy 4-0 defeat to Atalanta over the weekend. Meanwhile, Udinese stayed in 10th place in the standings.
