An overhead finish from Japanese international Shinji Okazaki was enough for the Foxes to claim a nervy 1-0 win over Newcastle United at the King Power Stadium.
Later tonight, there's another two Champions League quarter-final spots down for decision.
Man City will be expected to secure their progress as they resume with a 3-1 first-leg lead and home advantage tonight over Dynamo Kiev at Eastlands.
Meanwhile, Atletico Madrid and PSV Eindhoven are still deadlocked on nil-all as they resume their last-16 tie in the Spanish capital.
