It ends a run of three consecutive home league victories for the Foxes youngsters, who now sit fifth in the standings, remaining on 15 points from nine matches.
Tobey Ugorji scored both of the away side’s goals during the first half in Seagrave, converting a penalty on the half-hour mark, prior to finishing across goal just seven minutes later.
Another home fixture comes next in the division after the international break, with West Bromwich Albion the visitors on Saturday 29 November.
Before then, however, attention turns to the U18 Premier League Cup, with the side coached by Adam Barradell travelling to take on Aston Villa at Bodymoor Heath Training Ground on Saturday 22 November (both 11am GMT kick-offs).
