Head coach Michael Skubala said his team were gutted after City's 2-1 home defeat to Wigan Athletic, which saw his side's first loss in 17 matches, but they must 'keep going'.
Danny Mandroiu's spectacular strike levelled the scores prior to the half-time break, after Jonny Smith gave the visitors a first-half lead.
Although the Imps saw three goals disallowed, Charlie Hughes’ late strike sealed the win for Wigan.
Skubala said: "We're gutted because we wanted to keep trying to win. We know they're a good team but we had some chances. We started a little bit slow and it was the first time I've seen nerves in the group, but then we got in the ascendency but just couldn't find that extra goal.
"The lads give everything all the time and we're creaking a little bit because we probably haven't got the bodies all the time.
"We were hurt because in the end we tried to risk and get that goal, knowing the Oxford versus Peterborough scoreline.
"There are still nine points to play for so let's go to Oxford and give everything again, and see what happens after that."
As referenced by Skubala, the Imps make a quick return to action at Oxford United, who currently sit in sixth position and five points above City, on Tuesday night.
The head coach added: "It's not over yet. There are nine points to play for. We know we have to win every game and hope Oxford slip up. If we get the nine points then you never know. We'll keep going."
