Dominic Samuel took a step closer to first-team football for Town with 70 minutes for the U23s in the draw against Crewe.
The striker, on loan from Reading, made his comeback after six weeks out with a broken toe at Portman Road.
Samuel, whose only other appearance in a Town shirt saw him score a hat-trick for the U23s in a 8-0 win over Watford at the start of February after arriving on loan on transfer deadline day, joined Brett Pitman, Freddie Sears and Jonny Williams in a side that had more than a sprinkling of senior players.
Pitman put Town in front in the first-half, forcing the ball in shortly after he had seen his penalty saved.
Sears went close to extending Town’s lead but Crewe levelled through Daniel Udoh before the hour.
Adam McDonnell and Sears both could have won it for Town late on but Blues also had Michael Crowe to thank for producing an excellent save to deny Perry Ng.
