The former Southampton midfielder had been out for two months with a similar problem, but made his comeback a fortnight ago, playing in the Canaries' last two games.
But now the 24-year-old is back in the treatment room and will not play again this year.
"It's a blow because he's done really well for us since he's come back," boss Paul Lambert told BBC Radio Norfolk.
"He's got a problem with his knee at the minute and hopefully that will settle down and we'll get him back."
