Kerr went off with a knee injury in the first half at the Technqiue Stadium and Gavin Gunning pulled his hamstring after the break.
On Kerr, Spireites manager James Rowe said: “It is a bad one, we are not sure, we might need to scan it and see.”
And on Gunning, he added: “That is a bad hamstring one.”
The visitors ended Town’s impressive record of six home wins on the bounce when Donovan Wilson scored the only goal of the game 10 minutes before half-time.
There appeared to be a foul in the build-up and Rowe expressed his frustration after full-time.
He also felt that Kerr’s injury disrupted his side because it meant that George Carline had to move to the right of a back three and the left-footed Alex Whittle came on at right-back.
“It was a very even game, it was always going to be, and we lost it on a decision,” he said.
“It is really disappointing. At this stage of the season small details matter. I don’t want to just lump it on the referee but it has finished one-nil and it is a foul so at the end the result has been determined by the officials and it is an incorrect decision.
“I have seen it three times. Gavin (Gunning) is jumping and he has been bumped in the back so Gavin has obviously headed it off balance backwards and he (Wilson) has gone and smashed it in the net.
“I don’t want to take anything away from Sutton tonight, they are in that position for a reason but I don’t think it is right that a game like that should be decided in that manner, but we didn’t do enough to get back into it.”
He added: “It is disappointing but there are things we could have done better so I want to focus on that, I don’t want to focus too much on the referee. We didn’t create enough.
“Did we do enough to equalise? That is the question I need to ask when I reflect on it."
