But back-to-back defeats since then has extended Town's Championship losing streak to six games.
Keane was able to add an older head to his youthful defence with the return of Mark Kennedy on Saturday.
The 34-year-old left-back played just over an hour after making his second attempt to recover from a hamstring injury he picked up in October.
The former Cardiff defender, who has featured just eight times since arriving at Portman Road in the summer, suffered a setback when he tried to return to action last month.
"He's only trained two or three days with us and we've made that mistake before in terms of playing him," Keane said.
"We're always tempted to keep him on the pitch because of his experience but that's backfired on us before.
"We're pleased he's got 60-odd minutes under his belt."
