Etuhu, 23, incurred the wrath of his soon-to-be-former employers when his second half tackle resulted in a broken leg for Preston's Adam Nowland, who had earlier broekn the deadlock right on half time.
The former Manchester City man is believed to be ready to sign a three and a half year deal to stay at Carrow Road beyond his loan spell, and is likely to cost the club around £450,000.
