Town have drawn League One Doncaster Rovers away in the second round of the Capital One Cup.
Doncaster beat 10-man Leeds 4-2 on penalties after a 1-1 draw at home in this evening's live Sky game.
Ex-Blues loanee Richie Wellens netted the decisive spot-kick, while another one-time Town loan player, striker Chris Wood, was amongst those to miss for the Whites.
The Blues and Doncaster last met in the competition at the same stage in the 2004/05 season when the South Yorkshiremen won 2-0 at their former home Belle Vue with Ricky Ravenhill and Jermaine McSporran on the scoresheet.
Town's last visit to their current ground, the Keepmoat Stadium, was on Boxing Day 2013 when they ran out 3-0 victors - David McGoldrick (2) and Luke Chambers - with Rovers on their way to relegation from the Championship.
In the following April the Blues completed the double by recording a 2-1 win at Portman Road. Daryl Murphy and skipper Chambers scored for Town either side of Chris Brown's penalty for Doncaster.
In addition to Wellens, midfielder Richard Chaplow joined Rovers following his release by the Blues last summer.
Second round ties will be played in the week commencing 24th August.
