Palace have completed the signing of young goalkeeper Scott Flinders from Barnsley on a three year deal.
The 20-year-old has signed for an initial fee of £500,000 – though that could rise to £1m depending on how many appearances he makes for the Eagles.
Flinders is well-known to Palace boss Peter Taylor after making a number of appearances for the England U20 side.
Going the other way is Sam Togwell – who has joined the Tykes for an undisclosed fee.
