Town end their pre-season friendly programme with a visit to League One play-off finalists Leyton Orient on Saturday afternoon (KO 3pm).
The Blues remain undefeated in their five games so far — four wins and the home draw with West Ham - and have conceded just the one goal, at Southend on Tuesday.
Manager Mick McCarthy is likely to field a side which will probably be very close to the team which will line up against Fulham at home in the opening Championship fixture of the season next Saturday (KO 5.15pm, Sky Sports 1/HD1).
At some stage fans are likely to have another chance to run the rule over Kevin Bru and Balint Bajner, who joined the club yesterday having been on trial since the start of last week.
Winger Stephen Hunt is the only member of the squad currently sidelined, the Irishman, who celebrates his 33rd birthday today, having been troubled with a calf problem throughout pre-season.
The current O's squad includes former Blues striker Kevin Lisbie, while ex-Reading skipper Jobi McAnuff and one-time Hull City striker Jay Simpson are recent additions to manager Russell Slade’s ranks.
The sides last met in a senior pre-season friendly at Brisbane Road in the summer of 2000 when the game ended 2-2 with David Johnson and Tony Mowbray scoring for the Blues. Admission is £15 for adults and £5 for concessions.
Meanwhile, Town’s U21s are in action away against Skrill South side Chelmsford City in a friendly this evening (KO 7.45pm), while this lunchtime’s U18s friendly at Huddersfield has been cancelled.
