City boss Michael Appleton has set his sights on picking up enough points to ensure a relaxing end to the season.
Saturday's win at AFC Wimbledon put the Imps eight points clear of the relegation zone and Appleton wants to keep adding to the tally to keep the relegation scrap at arm's length.
He said: "Our focus will be to make sure we're not even in consideration in that scrap as a club, we want as many points on the board as possible.
"If we can put ourselves in a position with four or five games to go and knowing we are not even in contention for those spots then that's what we'll do."
The Imps face a tough test on Tuesday night as they head to league leaders Rotherham United. Appleton knows City will have to match the same work-rate and endeavour which saw them claim a point at the LNER Stadium earlier in the season.
He added: "Paul Warne sets his teams up to overpower teams from a physical and athleticism view - and they do really well at this level.
"So we have got to match them, or get as close as we can from a physical point of view, to give ourselves a chance to be in the game in the latter stages when the attacking-minded players have an opportunity to get something out of the game for us."
