Both sides mustered half-chances as the game went on, struggling to find a clear breakthrough to reclaim the lead. Reece Evans and Toby Ononaye had efforts for Leicester that were no issue for Billy Eastwood in the Palace goal.
With just over 10 minutes remaining, Derry hit the bar. Seb Williams found him out on the left hand side and the winger managed to flick it over his marker before racing towards the box. His strike beat the recovering defender and goalkeeper, but struck the bar.
The game trickled towards stoppage time and aside from a blocked effort from Marsh, there were no other attempts on goal. The result means Quinn’s side slip to second in the U18 Premier League South on seven points, two behind leaders Fulham.
