"Don was struggling a little bit, to be fair, with a calf strain - and that is why he wasn't in the 16," says Peter Grant.
David Connolly returned to the starting line-up with Marlon Harewood reverting to the right flank and Peter adds:
"Connors came in and did what you expect although you always want more from everybody.
"We would probably have made a change but Don would definitely have been in the 16 if he was fit."
Looking at the 1-0 defeat at Portman Road, he adds:
"There were some good things and some not so good; we probably started at a frantic pace and Ipswich had some good chances just before the break, so to be perfectly honest we thought 'thank goodness we got to half time at 0-0'.
"In the second half we still didn't look as big a threat as we should have with a lot of possession and a lot of nice things in that final third - without looking positive where everything counts.
"Defensively we coped quite well, and with some good things and bad things there has been some stuff to work on.
"But the good aspect of it is we are still in the tie, and it is a game of two halves as a two legged affair.
"We have got 90 minutes to claw that back and hopefully produce a performance and a result that will get us to the Millennium stadium - it will take nothing less than a victory."
Ipswich's goal after a rebound from the bar struck Tomas Repka was somewhat fortuitous and Peter shrugs:
"That is football for you; sometimes it hits the post and goes the other way, but it hit the post and went to a very good finisher in Darren Bent.
"We know it will be difficult on Tuesday because once they get a head of steam they can pass the ball and at times we didn't cope with that particularly well.
"I thought we gave the ball away cheaply, won it back, then gave it away again - and that is something we have got to make sure doesn't happen at Upton Park."
