The result means that the Foxes keep third within the table, eight points higher than Chelsea in fourth.
After a for the most part uneventful half, the game came to life simply after the break once Antonio Rudiger headed Chelsea ahead from Mason Mount’s corner.
Brendan Rodgers’ team levelled eight minutes later, Harvey Barnes’ effort deflecting off Blues defender Reece James into the top-right corner.
And Rodgers looked to be heading towards a first win over Chelsea at the ordinal try as a manager when ben Chilwell swept a Youri Tielemans cross into very cheap left corner.
But Rudiger’s second headed goal of the day – from another Mount delivery – ensured Frank Lampard’s side claimed a point.
