The former England international sat in the directors' box at Portman Road as Michael Chopra's 50th-minute strike settled the contest. While Blackpool are yet to confirm Ince's arrival, caretaker boss Steve Thompson revealed after Saturday's game that the 45-year-old was on the brink of agreeing a deal.
"There's going to be an announcement on Monday. It's going to be Paul Ince," he said. "The deal is very close to being done."
Ince has not managed since he left Notts County almost two years ago and his return will see him coach his son and England Under-21 international Tom Ince.
Thompson has been in interim charge since Michael Appleton left for Blackburn on January 11 and revealed he hoped to remain to help Ince on his return to management.
"It's something I want to do," he said. "It's quite difficult stepping in as number two. As much as you try and do things right, you always know that this time next week you might have your arm round a new manager as his assistant.
"I'll just have to see what happens. I think Paul wants me to work with his team. I'll keep my head down and work as hard as I can for him, but further down the line, I want to be number one."
