Commons celebrates scoring the winner on his old stomping ground
Derby County fought back from two goals down to beat local rivals Nottingham Forest and set up an FA Cup fifth round encounter with Manchester United.
Forest got off to a stunning start as Chris Cohen lashed in a left-foot shot and Nathan Tyson scored from the spot after Stephen Bywater brought him down.
But Rob Hulse headed home Gary Teale's cross and Paul Green nodded in another Teale centre to level it for Derby.
They won it when ex-Forest star Kris Commons struck with a 20-yard drive.
The stirring comeback gave Rams boss Nigel Clough the perfect return to the City Ground, where he represented Forest for so long as a player.
But it was a shame for either side to lose after a rip-roaring Cup tie between two fierce local rivals, with both sets of players giving it absolutely everything.
With Forest and Derby struggling towards the foot of the Championship there are more important battles to fight this season, but bragging rights were very much up for grabs on the banks of the River Trent.
It was the home team that made by far the better start and with only 37 seconds on the clock, they took the lead.
Cohen took a short corner and collected the ball back from Matt Thornhill, creating an angle to shoot and hammering it via a slight deflection into the top corner past Bywater.
Forest were flying and Tyson headed wide before Lewis McGugan's sweetly-struck volley flew into the arms of Bywater.
