Derby County boss Billy Davies will field four of his brightest prospects in tonight's friendly at St Mirren.
"It is a chance to look at a number of the young players who have been doing well in the Reserves, and we may look at one or two different positions and situations," said Davies.
"We will also play one or two players who need a game, so it's a good exercise for us."
Beardsley is an 18-year-old right-back who played in the Carling Cup defeat by Blackpool last month.
Addison, also 18, made two first-team appearances under caretaker boss Terry Westley at the back end of the 2005-6 season.
Hanson, 19, and 17-year-old Richards have yet to taste senior action.
