Keyframing a Bone that is Following a Path

Hello everyone, I’ve got a problem trying to get keyframe data for a bone that is following a path. The animation itself is fine, the bone (and the meshes parented to it) move through the path just fine, but I can’t seem to get any data from it back to the bone. This animation will get exported to an external game engine, so the bone must contain the data from the path (in the form of bone positions), and I just can’t figure out a way to do that.

Any ideas on how to accomplish this?
