Nottingham Forest are through to the third round of the EFL Cup after Lars Veldwijk's emphatic late finish saw the visitors beat Millwall 2-1.
Jamie Paterson slotted home to put Forest ahead, before Shaun Williams scored from 50 yards to give Millwall hope.
But Veldwijk fired into the bottom corner with extra-time looming.
Forest broke the deadlock on 35 minutes when Paterson fired in on the rebound after Veldwijk's header was saved by Tom King.
The Lions ought to have equalised in first-half injury...
