So you and the players sit on an unprotected bench during the game? If that is correct, I certainly would not be sitting there and take a chance on getting hit by a puck. Or my lens getting hit.
Hockey photographers do take chances when seated in, near, or between the benches or penalty boxes. Some use a typically unwanted filter in hopes that the lens just might escape damage in case of a hit. Helmets are common or required. To add to the challenge, they can be distracted looking into the viewfinder when an unexpected deflection comes their way. It obviously helps them to know the game. Yes, it can be a risky and challenging shoot, but they wouldn't have it any other way. The only pro I know is more more concerned with focusing on fast skaters and getting great shots than the risk of injury or damage.

What you state as fact is really your opinion which of course you are entitled to. In your statement, you acknowledge that the head of the person in not distorted. Well it should be unless you are suggesting this is a composite of two images: one with pincushion and the other without. You can’t have it both ways.
The undistorted image of the player’s head, and the pincushioning of the grid (of undetermined origin) are incontrovertible evidence that one CAN have it both ways. You have but to trust your eyes.
Now all we lack is an expl@nation.

With a careful look, aren't the two pincushion banding patterns very similar in 1 and 2? Since we learned there was little or no cropping, that leans toward an artifact in the lens with significant contrast enhancement to bring this out. The unrelated grid in #2 struck me right away as a picture of a protector net but since it didn't seem possible it could appear in the photo, I looked for an artifact of some sort. That's why I wonder if the image was tilted in post. If not, then it has to be an an image of something real due the angle (and also the slight irregularity) of the lines. The examples of mirror-like reflections in some of the very useful replies helped me see where it could be a reflection. I would love for brooklyn to go back to the same bench with the same lenses and similar lighting to try to re-recreate the results and post the RAW. Maybe he will do just that despite his rigorous shooting schedule. We would greatly appreciate it.

Have you ever watched a hockey game?? The player's bench is unprotected. That is how they get on and off the ice.

So far this reply makes the most sense. Thank yo Diamond41

Sorry no plexiglass at all or glass.

It does, that is why I think it is something being reflected onto the filter. The plexiglass has probably picked up a reflection of the net and passed it onto the filter. The distortion being changed as the angle of the lens/filter changes.

Let me clarify my statement, yes I understand that there isn't any glass in between you and the ice, I'm a former skater, and I understand how the player's and penalty boxes are designed without glass between the boxes and the ice. The glass is behind those boxes.
But above the glass around the rest of the rink, is there any netting protecting the spectators from errant hockey pucks?
It's this netting that I believe is the source of your "reflection" in your shots.
It's a fluke of the angle of the shot to the angle of the netting reflecting from the lens to the filter, and being captured by your sensor.
The difference between standing and shooting forward, or sitting, and shooting slightly upward could cause the reflection.

Just a guess. Were there nets above or near the subjects? Perhaps at a high ISO the camera is picking up shadows that cannot be seen with the naked eye?

Consider contacting the manufacturers of camera, lens and filter manufacturer, submit the photos and get their opinions. Then let us know their input, if any.
For my 2 cents longshot guess, i suspect this might be a temperature / settings / firmware sensor (AA filter or other sensor coating) / processor issue - just by chance winning the distortion lottery. Although possible, I put less into the filter hypothesis because the odd overlay is too sharp looking (typically focusing at a good distance away would blur through filter scratches or other glass and reflection oddities).
Since this is a rare not a recurrent issue, likely nothing to be much concerned about. To satisfy curiosity I would suggest, though, revisiting the rink from same shooting spot and trying to reproduce the problem. If it recurs then remove the lens filter. Then adjust other shooting variables one at a time and see what happens (take notes). Then try a different lens. Shoot in jpeg + raw. Keep these files and examine further, submit for review here and other forums.

The cause is could be the warm air trapped between the filter and the lense. Once the air between the filter and the lense cools to the ambient, does the problem go away? I’ve shot hockey from the bench before and it is cold there. I am usually there during warm-ups (sic), so my equipment does have time to acclimate to the environment.

Looking further into this, I think another possibility would be how adjustments were made in Lightroom and that through an unfortunate mix of settings, the reported artifacts were created as a result. For instance, read through these comments here:
