Barcelona B twice let a lead slip to draw 2-2 with Tenerife on Sunday evening.
Jean Marie Dongou scored after just four minutes to give the home side the lead before Diego Ifran equalised on 13 minutes.
Patricio Gabarron netted from the penalty spot on 24 minutes to give Barca the lead once again.
However, the hosts were reduced to 10 men when Dongou was shown a straight red card just after the half-hour mark.
The visitors then restored parity on the hour mark when Maximiliano Perez struck to earn the draw.
