Adem Ljajic scored deep into injury-time to rescue a point for second-placed Roma who had to come from two goals behind and with a man down to earn a 2-2 draw at home to Sassuolo in Serie A.
Ljajic had begun the comeback with a 78th minute penalty for a Roma side reduced to 10 men six minutes after the break when midfielder Daniele De Rossi was sent off for a second booking.
Rudi Garcia's team stayed three points behind leaders and titleholders Juventus, who drew 0-0 at Fiorentina yesterday, after dropping their first points at home in the league this season.
Dutch midfielder Kevin Strootman started his first game for Roma since last March when he injured his left knee, forcing him to miss the World Cup.
Simone Zaza silenced the Stadio Olimpico crowd with two goals in three minutes, the first courtesy of a blunder by Morgan De Sanctis.
The Roma goalkeeper took too long in trying the clear the ball and Zaza intercepted and slid the ball into the net in the 15th minute. Three minutes later, Zaza escaped the offside trap and powered his shot past a helpless De Sanctis.
Roma's best chance of the half was a Jose Holebas effort from a tight angle which Andrea Consigli just tipped onto the crossbar.
Roma seemed to be chasing a lost cause after De Rossi's dismissal but a controversial penalty with 13 minutes to go, awarded for handball by Sime Vrsaljko, allowed Ljajic to reduce the arrears.
The Serbia international found the back of the net again in the third minute of stoppage time, side-footing home his sixth league goal of the season after Alessandro Florenzi got to the byline and pulled the ball back.
"We are disappointed," said Ljajic. "I'm not sure what happened at the start, we didn't seem ready. But after going down by two goals we dominated. Too bad we came away with just the one point."
In the late game, struggling Torino twice fought back to force a 2-2 draw at home to Palermo but the Stadio Olimpico club remained without a victory in their last seven games.
Josef Martinez's first goal in Granata colours cancelled out Luca Rigoni's opener before Kamil Glik responded to a clever finish from Paulo Dybala, who has now scored for Palermo in each of his last five appearances.
The point did little to soothe the pain still felt by Torino in the wake of their cruel derby defeat to Juventus, but it did mean they have a three-point cushion above the bottom three.
Palermo, meanwhile, climbed to 11th in the table.
