Osasuna are still without a win in La Liga this season after they were held to a 1-1 draw with Mallorca at El Sadar.
A goalless first half was marred when Joseba Llorente and Nunes were both sent off for fighting.
The home side eventually took the lead with 20 minutes to play as Kike Sola got on the end of Roland Lamah's cross to head past Dudu Aouate.
However, Mallorca equalised 10 minutes later when Emilio Nsue set up Tomer Hemed who headed in.
