The Australian midfielder has been unable to break into Neil Warnock's starting line-up this season due to the form of Neil Danns, Alassane N'Diaye and Darren Ambrose.
"Neil is the manager and he makes the final decisions, but the bottom line is that Nick has never whinged, never complained," Jones told Palace's official website.
"He is the first to congratulate the players if they get a good result, and he is very unlucky to be out of the team at the moment. But the system we are playing suits the players we have got and he knows that.
"Dannsy has become a better player because of Alassane, who, while he is still naive and a bit raw, opens the gaps up for him and Ambrose.
"So the balance of the team at the moment looks very good and Nick has been a victim of that. But he is still a very good player."
