Blues failed to repeat their comeback heroics at Blackpool last weekend as they slipped to a narrow defeat at Portman Road.
The only goal of the match came the way of Ipswich Town's Daryl Murphy in the first-half as Blues failed to upset the Tractor Boys on their own patch.
After a scrappy first-half in which Blues largely edged proceedings, Ipswich were gifted a 39th opener. Frank Nouble's low cross from the right wasn't dealt with, handing Murphy the simple task of tapping home at the far post.
Paul Caddis made way for Liverpool loanee Jordon Ibe at the break while Chris Burke entered the fray for Federico Macheda 13 minutes later. The latter made an impact within five minutes by teeing up Lee Novak for a close range effort that went high and wide from a narrow angle down the left - arguably Blues' best chance of the match.
Blues had a handful of chances during the first-half. In the 12th minute, Nikola Zigic closed down a clearance to set Macheda on his way but Christophe Berra got back to make a last-ditch challenge as the Italian was ready to pull the trigger. Then, six minutes later, Novak caught the Ipswich defence napping and beat the offside trap only to fire his shot just wide of the mark.
Nouble had been a particular thorn in the side of Blues and fired a warning shot, a scuffed effort from 12 yards that was easy for Darren Randolph to gather, in the 37th minute. However, Blues only had themselves to blame when the former Wolverhampton Wanderers man delivered a low ball that slipped under the flailing boot of Aaron Martin to find Murphy arriving for 1-0.
Ipswich were in no mood to let that lead slip and Randolph had to be alert, and at full stretch, to tip away a Paul Taylor shot that was bound for the right corner in the 57th minute. Then, in the 82nd minute, the Republic of Ireland goalkeeper was well placed to save Aaron Cresswell's close range header after the left back had found himself on the end of a Paul Green delivery.
Blues tried to force an equaliser but, and in Lee Clark's own words, were ultimately lacking that bit of quality going forward in what was a largely uneventful game.
