David 'Spud' Thornhill says he has been left amazed at the reaction to his unexpected involvement in Saturday's game against Preston North End.
The City fan, who is a qualified referee, took over fourth official duties for the closing stages following an injury to one of the linesmen - leading to widespread coverage from a multitude of sources.
"It’s been crazy and I’m overwhelmed by the attention I’ve had if I’m honest," he said after his performing his impromptu duty at Carrow Road.
"I’m pretty modest and I didn’t have to do anything really apart from hold the board up a couple of times! I just wanted to help out."
Saturday wasn't the first time David had operated as fourth official at Carrow Road, having performed the role for the duration of a pre-season friendly against Everton in 2010.
He also stepped in during four matches between 2001 and 2009, when injuries to officials required him to do so.
"One of the stewards knew I’d done it before so that is why I got asked," he explained in an interview with the Eastern Daily Press.
"I was sitting in my brother’s seat in the front row of the City Stand near the dugouts, so I was pretty close by. Seeing my chest on TV wasn’t my finest moment!"
