It's fairly straightforward. If you need to, export a still frame of the image from AE, or otherwise use the original source.
Open in Photoshop and make two duplicate layers of the whole image. It's not essential, but personally I always retain the background layer as the original contnent, so there's always a backup if you need it.
On the upper layer, erase everything except the player. Use whatever tools you prefer - masks, eraser, the selector tools, whatever you like.
On the lower image, use the Clone Stamp tool to clone areas of plain grass over the player, effectively painting him out. With some careful cloning you should be able to rebuild the white field marking below him.
Save the document and import to After Effects as a Composition. You'll now have a clean background layer and an isolated player that you can animate over the top.
