Porto led by two goals in their match against Braga but they let the win slip away in the final minutes.
Sérgio Oliveira (POR) scored the goal for the lead at 35 ‘, from the penalty spot. Jesús Corona (MEX) gave the pass to goal for Mehdi Taremi (IRI) at 54 ‘. It was a great cross pumped from near the outside line towards the head of the Iranian.
Braga did not give up and scored two goals close to the end of the game. Fransérgio Barbosa (BRA) scored at 87 ‘and Nicolás Gaitán (ARG) at 90 + 4’, in a pair of lapsus.
Bitter draw as Sporting is five points ahead and has a match on Tuesday against Gil Vicente, 13th in the Primeira Liga.
This is the first match since Nanu (GNB) suffered a head clash and is still in hospital.
