Niasse and Keane missed out on playing for Everton against West Ham United in the week, and despite their absences the Toffees’ excelled.
Everton picked up a 4-0 victory over West Ham United, to lift the mood around Goodison Park.
But Allardyce is keen to get Niasse and Keane involved again, and has confirmed that they will be in his match day squad to face Huddersfield Town at the weekend.
He said: “Niasse and Keane are fine. We are happy to have them back in the squad. We only had four players on Wednesday.
“Fatigue may be a factor. Substitutes might be a big play if we see anybody tiring.”
Niasse missed out on playing against West Ham due to suspension, with Dominic Calvert-Lewin leading the line in his absence.
Keane, meanwhile, was not selected due to a knee problem, but he has shaken off that complaint now.
Everton’s win over West Ham has lifted them up to 13th in the Premier League table, and there is hope that the Toffees can now push on.
Everton have been highly disappointing over the season so far, but a win against Huddersfield could lift them into the top half of the table.
