Without actually appearing in La Liga, Antón was an unused substitute in Bernd Schuster's last game in charge of the first team, a 3–4 home loss against Sevilla FC on 7 December 2008. The following match, a 0–2 defeat at FC Barcelona in Juande Ramos' debut, he was again on the bench.[1]
Antón signed for UB Conquense on 30 January 2015, receiving the international clearance seven days later.[3] He continued competing in division three in the following years, with CD Guijuelo[4] and CD Eldense.[5]
