The strikers both missed Norwich City's opening pre-season match against Vallee d'Aoste in Italy earlier today with leg and Achilles problems respectively.
The manager told the club's website: "Kyle trained on his own today and we're hoping he'll train with the team this week and be available for the next game.
"With Lewis, there was a little bit of soreness in his Achilles so it was a precaution that he didn't train or play today. Hopefully neither it too serious at all."
The Canaries beat their Serie D opponents 13-0.
