Northampton Town will make the short journey to Kenilworth Road to take on Blue Square Premier Luton Town in the FA Cup 1st round.
The tie will be played over the weekend of November 12/13 and could be a candidate for live TV coverage.
Meanwhile, Rotherham manager Andy Scott was pleased with his side's display in Saturday's game at Sixfields.
"The performance was a lot better than in recent weeks and we looked far more resolute," he said after the 1-1 draw.
"But if we had showed more quality in the final third I'm sure we would have won the game. We lacked a little bit of quality in the box and also a bit of luck, but we also had to defend a lot from Northampton's aerial threat, which I thought we did really well.
"It's disappointing not to be leaving with a win but I am still pleased with the performance."
