In stoppage time, it probably should have been three for Newcastle; after Henderson made a fine stop with his legs from Barnes, Joe Willock swept the rebound wide from six yards out.
In the end, Newcastle’s greater momentum in the second-half told – but even five minutes into stoppage time, Palace were seeking a route back into the game, Mitchell the Eagles’ furthest player forwards and causing panic in the box with a header back across goal.
A hard-fought battle which ended in defeat – Palace now turning their attentions to the visit of Aston Villa to Selhurst Park on Wednesday evening.
