In Photoshop, you would probably have a hard time removing the ball and boot with content aware fill. I would approach it from a more traditional technique that's sure to work
Create a new layer above the original. Select/Highlight this layer.
I would start with the Pen Tool making an outline of the low/missing portion of the jersey.
Right click and make a selection.
I would then Use the Clone Stamp Tool and the Brush Tool to fill in the selection.
Using the Brush Tool, match the shading.
It will be almost impossible to match the gradation of the background...........so let's borrow from the top and use that to cover the remaining ball and boot.
Select/highlight the original layer and use the Rectangular Marquis Tool to make a selection of the upper portion of this image. Once you have the selection hit Cmd/Cntrl + J to copy the selection to it's own layer. Move the copied layer to the top of the layer stack.
Hit Cmd/Cntrl + T and flip vertical. Use the Move Tool to move it down into position. You will find positioning easier if you lower the layers opacity.
Remember, your tring to match the gradient in the background.
Once you have it lined up, add a layer mask to the layer. Use the Brush Tool to blend.
All that's left to do is to Clone out the top of the ball. Use your Pen Tool path you made earlier, turn it into a selection again and invert it by hitting Shift + Cmd/Cntrl + I, this will mask out the area of the jersey so you don't have to worry about messing it up.
The rest is Clone and Brush work to finish off the ball and the duplicated text!
