The midlands have made a habit this season of conceding late goals, and they proved particularly costly in the matches against Brighton and Swindon Town.
Hobbs spent part of last season on loan at Scunthorpe, and Saturday will be his first return to North Lincolnshire.
"We've been through it and, if there are to be late goals, they should be at the other end this time," he told the Leicester Mercury.
"I think we just needed to kill off the Swindon game. We sat too deep, perhaps, and invited pressure on ourselves.
"But we've debriefed, looked at the clips of that game - and the ones against Brighton and Huddersfield - and hopefully, if it comes to that, we're going to stop it this time."
