Mark Warburton's Reds head down Brian Clough Way this weekend for the first East Midlands derby of the season. And it's been revealed there are still some tickets available in the home stands.
Forest sold out their allocation on October 3, with all 3,127 tickets snapped up by Reds fans.
But with three-and-a-half days to go before the big showdown, Derby could not say the same.
Former Forest forward Garry Birtles believes the derby could be pivotal for both teams.
"I think this could actually turn out to be a pivotal game for both clubs," he said.
"Forest had that fabulous win against Sheffield United last time out – it's exactly the kind of result you want before an international break, and before a derby match. Forest will hope that Sheffield United game was a turning point for them, whereas Derby will hope theirs comes on Sunday They haven't won in their last five games and will be looking to turn things around this weekend."
