Jonjoe Kenny was in the side, almost certainly ruling him out of any involvement with the first team tomorrow, along with Luke Garbutt and new signing Josh Bowler.
Anton Donkor was named among the substituted with the more experienced Conor Grant and up-and-coming striker Nathan Broadhead.
Broadhead would find himself in the action sooner than expected when Calum Dyson was forced off with an injury in the first half.
And after a goalless first period, in which Bowler had seen a shot blocked, Broadhead himself had to be substituted, replaced by Grant with Sambou left as a lone striker up front.
The 21-year-old's presence added to Everton's ability to control the midfield and they were in the driving seat as the second half progressed.
However, Michail Antonio tested Louis Gray with a strong shot from outside the box that then 'keeper was equal to.
Kenny came closer than anyone to breaking the deadlock when he rattled a shot off the post before Morgan Feeney's header was saved and Sambou came within inches of connecting with a ball in front of goal.
Conor Coventry was sent off for the home side as the game moved into stoppage time.
Everton U23s: Gray, Kenny, Jones, Garbutt (76' Donkor), Connolly, Baningime, Charsley, Feeney, Bowler, Dyson (16' Broadhead (46' Grant)), Sambou.
Subs: Renshaw, Foulds.
