Keane was left out of the squad for Sunday's FA Cup game against Everton but has been recalled for tonight's Premier League game against Wigan at the JJB.
"Robbie had a day off on Sunday, he trained on Monday and today as normal - he will be in the squad for tomorrow," said Rafael Benitez.
"We are just thinking about using him in tomorrow's game. I will be very pleased if he can score against Wigan Athletic.
"He is working very hard and will be a very important player for the rest of the season. Keane is in the squad so we don't need to talk too much about him."
