The young Foxes got back to winning ways in Premier League 2 earlier this week by overcoming Norwich City, before travelling down to east London four days later.
It looked to be going the way of the home side at Rush Green after Regan Clayton set up Andre Dike to break the deadlock half an hour into the contest.
The side coached by Leon McSweeney kept on battling and earned a reward six minutes into injury time when Bobby Amartey, up from the back, assisted Kirsten Otchere's late equaliser.
Now sixth in the PL2 standings, on 24 points from 15 matches, we host Manchester United at LCFC Training Ground on Monday 23 February (7pm GMT kick-off).
