The 23-year-old, who in the first part of this season was assigned by the 'lions' to the Turks of Antalyaspor, in whom he played only nine matches and scored a goal, is back in Vila do Conde, where he will remain until the end of the season.
In the previous two seasons, Gelson Dala had already joined the Rio Ave squad, also on loan from Sporting, having participated in 32 games and scored eight goals in those passages.
The Angolan international striker, who has trained with the Vila-Condense working group and chose jersey number 57, is Rio Ave's first reinforcement in this reopening of the transfer market.
