Meanwhile, the quartet of Abba Suleiman, Victor Arikpo, Shedrack Asiegbu and Chibuzor Eze-Ogbodo are also available for selection after shrugging off injuries to be fit for the game.
The players also missed the first-leg tie at the Godswill Akpabio International Stadium, Uyo.
Rivers United will battle USM Alger at the Stade du Juliet on Sunday.
The former Nigeria Premier Football League champions hold a 1-0 advantage going into the game.
