Sevilla held at home by Deportivo
Defender Federico Fazio put the Andalusians ahead with a glancing header in the 21st minute at the Sanchez Pizjuan but Depor were level three minutes later when striker Adrian Lopez netted from an Andres Guardado cross.
In other matches on Saturday, Real Mallorca's woeful away form continued when they lost 3-0 at Getafe.
The Balearic Islanders, who have won 11 in 12 at home but only two in 14 away, remain fifth on 43 points, one more than sixth-placed Depor and two ahead of Athletic Bilbao who are seventh after a 0-0 draw at Sporting Gijon.
Goals from Daniel Parejo and Miku and a Manu Del Moral penalty earned the points for Getafe, and Mallorca's Portuguese defender Nunes was dismissed for handling on the goalline, an incident that led to Moral's spot-kick in the 85th minute.
Gijon goalkeeper Juan Pablo saved a 59th-minute penalty from Bilbao midfielder Igor Gabilondo to deny the Basque club all three points at a rain-lashed Molinon stadium.
