The Peruvian international striker joined the Tehran-based team more than one month ago but has yet to play for the team.
“Rinaldo will take part in Esteghlal’s training session on Saturday. His groin muscle was stretched 10 days after he joined us but the good news is that he is fully recovered now,” Esteghlal doctor said.
Rinaldo has no kind of injury at the moment, Amin Noruzi added.
Iranian media have reportedly said that the striker is suffering from a long-term injury.
Rinaldo, who has 11 caps, has made his debut for Peru on 11 May 2006 against Trinidad and Tobago.
