The 2017 Segunda División season, also known as Copa Best Cable Perú 2017 for sponsorship reasons,[2] was the 72nd edition of the second tier of Federación Peruana de Futbol.
In turn, Defensor La Bocana was relegated to the Segunda Division after a short spell of one year.
[3] Kola San Martín, Deportivo Garcilaso, and León de Huánuco expressed interest in taking Alianza Universidad's slot in the tournament.
Leon de Huanuco's appeal to the Court of Arbitration for Sport to return to the first division was denied and the Peruvian Football Federation relegated them to the 2017 Copa Perú's departmental stage.
Because Sport Boys and Universidad César Vallejo finished the regular season with the same number of points, a title play-off match will be played on neutral ground to decide the champion and owner of the 2018 Torneo Descentralizado berth.
