The visitors took the lead on eight minutes, after a fine passing move allowed Omar Perez to tap into an empty net from three yards out.
However, the home side managed to equalise on 66′. A perfectly weighted through-ball allowed Caio to clip in an expert finish over the goalkeeper to make it 1-1.
The home side would have been disappointed that they were not able to take an advantage into the second leg in Colombia, which takes place on October 25.
Whoever wins this tie will face either Velez Sarsfield of Argentina or Chile’s Universidad Catolica in the quarter-finals.
