Ghanaian attacker Issahaku Abdul Fatawu came on in the final twelfth minutes of Sporting Lisbon's 3-0 defeat to FC Porto in the Primera Liga.
Evanilson opened the scoring for Conceicao's side, before Mateus Uribe doubled the lead for Porto.
Galena compounded the worse at the Estádio de Dragao for Sporting Lisbon, as he increased the tally to three.
The 18-year-old made his second appearance after coming off the substitute bench again against Rio Ave last weekend.
Abdul Fatawu joined Sporting Lisbon in January from his Parent club Steadfast FC during his loan with Ghana Premier League side Dreams FC.
He initially featured for the junior side after his move before turning eighteen in March.
The former Steadfast FC winger made his debut for the Ghanaian National team in October last year against Zimbabwe and will hope to make it to the FIFA World Cup in Qatar.
