The defender had been on loan at Vasco from Desportivo Brasil, and his solid performances alongside Dede had seen him touted for a potential call up to the Brazil squad.
Some sources are speculating that the move is merely to facilitate Martins joining Paris St Germain, who are Qatari-owned, next year.
Martins will be replaced by Renato Silva in the Vasco line-up for Sunday’s game against Flamengo.
