Belper Town’s Mick Norbury has stepped down from his role as assistant manager to Grant Black.
The club say he tendered his resignation on Friday and the players were informed of the decision after the match at Frickley Athletic the following day.
Chairman Ian Woodward said: “We have had a number of conversations with Mick since he made his decision but we fully respect his wishes.
“He has been a brilliant asset to the club and we cannot thank him enough for the work he has done for us. We wish him well in whatever he decides to do, moving forward.”
