Sir Alex Ferguson will assess Cristiano Ronaldo's fitness before deciding whether to throw him back into the fray against Norwich on Saturday.
Ronaldo has returned to Manchester United after Portugal were knocked out of the Olympics, and Ferguson will make a decision after Friday's training session.
United continue to be without eight senior players, and after losing the opening game of the season against Chelsea, need a strong performance against the Canaries.
However, things are looking up for United as Darren Fletcher completes his suspension against Norwich, Kleberson resumes training on Friday and French striker Louis Saha will be back kicking a ball next week.
United (from): Howard, Carroll, Ricardo, P Neville, G Neville, O'Shea, Silvestre, Keane, Fortune, Miller, Djemba-Djemba, Scholes, Smith, Giggs, Richardson, Bellion, Forlan, Ronaldo.
