After a scramble in the area Andrew Lonergan upended David McGoldrick who duly slammed home the resulting spot kick.
All that after an encouraging opening 45 minutes in which Bolton’s attacking play impressed, with Lukas Jutkiewicz the focal point of the frontline.
“Once again we’re on the end of a very disappointing result,” the manager said after the game.
“Not for the first time we felt we were by far the better side in the opening 45 minutes. We competed very well and created four or five opportunities and it was a shame we didn’t take any of those.
“At the start of the second half a rush of blood and a rash decision was the difference between the two teams. Aside from that, there wasn’t a lot in it.
“We have no complaints about the penalty decision. That small moment won the game for Ipswich.
“Unfortunately, that’s the way things have been going for us recently.
“A disappointing thing from our point of view was the fact that we didn’t really create that much in the final 20 minutes when we were chasing the game.
“It’s obviously a concern that we’re not winning games of football at this moment in time, but we’ve got a group of good players here.
“We can’t let our heads go down. We have to make sure we keep the performance and commitment levels up.
“We have a number of big games at home coming up this month and we have to be right at it from the off.”
