Not really. You really need a clean plate, regardless whether that's a second clip or photo or you need to create it by rotoscoping and cloning. Displacement effects only do what the name implies - move pixels around and interpolate them. They don't magically create something out of nothing.
You need a cleanplate, but if you don't have a clean plate filmed, you can try to create one with object removal techniques.
You can, for example,do a rough rotoscoping of your player and then try to fill the hole with material from other frames. If your camera is not moving, you can do this by creating several duplicates of your clip (the one with the hole) and shifting them in time. If your camera is moving, you need to combine this with tracking, as I show in the following tutorials (the tutorials show how to fill the black borders of a stabilized clip, but the technique shown in chapter 5 can also be used to fill any other hole, like your rotoscoped player; and you can set the stabilization amount to 0% to do not have any stabilization).
Whether this approach will work depends on whether your background is changing a lot over time or not.
If you have a cheering, moving crowd in the area that you want to fill, it won't work, if it is just green grass, it is worth trying.
And here are some tips how to do the rotoscoping:
