What are these lines from?

I believe it is a reflection from the lights, perhaps hitting the ice and then the camera. I've had this type of thing before when I took a shot indoors under fluorescent lights. Probably not good to delete the RAW file, ever, at least that is my advice for future photos.

Yes there is netting above the glass the entire rink.

The lights are fluorescent.

Are you using the anti-flicker feature on your 7DII?
When enlarged the lines look like a net or screen. At high ISO and with the filter as extra reflective surfaces you could be getting a reflection/shadow of the netting that is just too faint for your eyes to see. The warping would be from being reflected and the angle(s) the light reflects at. There might even be a very thin/faint fogging on a surface that makes the reflection/shadow show up and after the lens and filter along with the air between them reach temperature equality it disappears and the sensor no longer has anything it can record.
Digital can see things our eyes can't I have recovered old faded receipts by photographing them or scanning them and then playing with the contrast to produce easily readable images that look blank or just a bit off color to the eye. I am a history teacher and tried it the first time after reading about similar things being used on old documents and paintings.
Just a thought to consider.

Not shot through anything except air. Shooting from the players bench, no glass, no nothing.
but what was across the ice? seems like in photo #1 its a reflection off the glass across the ice with caused the moire effect, which happens with 2 patterns that cross over each other...

Yes the Anti-Flicker is on.

No glass....shots are from the players bench.

Had a clear UV filter for protection.
Protection from what, a hockey puck? Good luck with that.
The best advise you've received here is to lose the filter. The pattern is from the net above you, it's reflecting off the curved face of your lens and landing on the back side of your flat filter. This is what's causing the pincushion effect of the pattern. 
I hope you haven't given up and stopped reading the replies. In all fairness, the cause of your issue was not immediately obvious, at least not to many of us, myself included. If it were, you wouldn't be here asking the question. You had a lot of people scratching their heads and trying to think of a viable explanation. IOW, they were trying to help you find the answer.

After removing the filter, it would be nice to hear about the results from the next game. I hope it solves your problem.

Everyone has been trying to offer suggestions with the best of intentions but many of us initially overlooked this statement. It rules out a lot of the speculation.
The problem cannot be the lights, reflections, flare or the protective filter. They were present for all of the unaffected images, 98% of the total. So you should examine:
1. In the first 20 images, did the problem go away gradually? Then it might be the camera temperature reaching a steady state and staying there for the rest of the game.
2. Did the problem go away suddenly when you changed from ISO 6400 to 3200?
3. Did you do anything different in post processing the first 20 images that you did not do for the others?
You posted only three images for us to examine but you can answer these questions by looking at the others.

Can you rule out the lights ? Many industrial lights are quite slow to turn on and become steady. Initial photo's may perhaps have been within that warm up period. could the shutter speed be capturing part of an ac wave? was anyone using flash initially? Perhaps that light outside the netting might have had an effect.

You probably can rule them out unless they had just gotten turned on a few minutes before the players showed up. Someone had to inspect the ice even before that.

Thinking about the issue further - I'm skeptical that the distortion is gear related. More likely it stems from post processing. That said, without the problem being reproduced by the OP or someone else, it's difficult to know conclusively and we're pretty much left with speculations. One thought, maybe OP can try using a file recovery utility to see if the raw files can be resurrected (presumes that the the hard drive space used by the raw files has not been overwritten by other data).

OK will do.
