Eagles boss Warnock's insists the former Peterborough frontman is staying at Selhurst Park despite playing second fiddle to Fraizer Campbell.
"Dwight is going nowhere because he is far too important to us," said Warnock.
"It's unfortunate for him that Fraizer Campbell is playing as well as he is, otherwise he would be in the team.
"I know Fraizer made a mistake in the Manchester United game, but aside from that he has been excellent for us.
"Dwight is second behind Fraizer, but it is no surprise to me that we've had interest from three or four Championship clubs."
