Tenerife, Xerez and Real Zaragoza all secured promotion to the Primera Division on Saturday with one round of fixtures still remaining in the Segunda Division.
Leaders Tenerife edged Girona 1-0, while Xerez were 2-1 winners over Huesca to ensure their place in the top flight for the first time in their history.
Zaragoza's 3-1 victory over Cordoba seals their return after just one year in the Segunda Division, with fourth-placed Hercules unable to catch the top three.
The destination of the title will be decided next weekend with just one point separating the leading trio.
