What does "walk it off" mean here? Doesn't "walk it off" mean to "bear with it" to someone who is slightly injured during a game?

You are kind of correct. The phrase "walk it off" simply means that you attempt to fix it reduce the pain felt from an injury, typically a leg or foot injury, by walking until the pain go away. It can be used in any situation and is not only connected to a game or sports. As you can see in this clip, no game is being played, but the phrase is still acceptable. Ex: I'm sure it's only a bruise. Just walk it off Ex: You can't walk off a stomachache. Take some painkillers!
