Palace have now lost consecutive home League games and find themselves outside the relegation places on goal difference only.
After a bright start by the home side it was the visitors who took the lead. Simon Church putting Reading on their way to a 4th consecutive League victory.
Palace missed more chances and were made to pay again when Jimmy Kebe made it 2 - 0 to Reading just after half time.
There was hope, Sean Scannell pulled one back with plenty of time to go but it was Reading who scored again with Church converting his second 9 mins from time.
Worrying times at Selhurst Park as far as the League goes.
Next up it's another home game, Coventry are the visitors on Saturday.
