The game is scheduled for Wednesday 19 March and if you want your ticket then you should get down to the Nottingham Forest ticket office as soon as possible.
Forest have raised ticket prices as indeed Derby did when we visited them. Forest Chief Executive Mark Arthur told the clubs official website how the East Midlands grudge-match was a premium fixture.
He said: "Our meeting with Derby is, without doubt, our biggest game of the season and we felt an increase in ticket prices was justified."
The 0-0 stalemate at Pride Park earlier in the season should be nothing to go by as this game looks set to be an absolute cracker.
The last time Forest faced Derby at The City Ground was November 1998 and this year's game will undoubtedly be a complete sell-out.
