The 31-year-old former Brazil international has been training with the Trotters recently.
“He has undergone several tests and was highly praised by the staff,” Denilson’s brother Denis de Oliveira Araujo told Gazetaesportiva.net.
“They said that, despite not playing for a month, he has the same conditions of the other players.”
“Bolton board members told us that Denilson’s situation has to be settled on Wednesday,” he added.
“I am optimistic – they gave him the key of the closet of the training centre.”
