Leicester remain one point ahead of West Brom in the U18 Premier League table, after 24 games, following a draw at the Fitlife Foods Performance Centre last weekend.
Fletcher opened the scoring after 19 minutes, but a second half equaliser from Dexter meant the points were shared.
Having played one or two more than others around us, we sit fifth in the standings with 35 points accumulated from 24 games; one point ahead of Saturday's hosts who have played 22.
With four games remaining this term, the young Foxes are back on home soil when they welcome Norwich City, who sit second bottom in the table, to Seagrave this Saturday afternoon (12:30pm BST kick-off).
This is followed by a trip to Southampton, a final home game against Arsenal at the start of next month, before concluding the season at the home of the current league leaders, Chelsea, on Saturday 9 May.
