David Nugent struck his second and third goals of the week to give Leicester City a narrow lead at the half-way stage against Hull City at the King Power Stadium.
The 27-year-old, who scored his 100th career league goal in Wednesday's 2-1 win over Burnley, broke the deadlock on seven minutes with a low left-footed drive from 12 yards.
Jay Simpson levelled the scores on 26 minutes, but Nugent restored his side's advantage with a well-placed header three minutes before the break.
Leicester have registered four shots, compared to their opponents' two.
