WALL OF TEXT WARNING

Hi all. I'm in the final stages of the application process for a high-paying, high-end product sales position. A close friend of mine vouched for and recommended me (we worked together in the military and in operations for a tech F100 company) to his manager, who jumped me ahead through the application process. 

I interviewed extremely well, smoked the aptitude exam, and was told by manager that he would love to have me on his team. The final step is the background check. 

Now, my background is clear: no criminal record, not fired, done well in previous positions. 

Here's my situation: during my last overseas deployment I injured my back. After leaving the military I rehabbed my back, and got my personal trainer certification (I power lifted and liked fitness). Was hired for a part time training job at a local gym (while working full time).

 I go to my first day of admin in-processing at gym, then go work out at said gym. Within 20 minutes, I reinjure my back. Wife had to get me, go to ER, will be in bed for 3 weeks; eventually led to surgery. After a few days, I called gym manager, and we agreed that this job would not be conducive to my recovery. I resigned within days of starting. 

I never list this job on anything since I didn't do anything and it doesn't add anything to my work experience. It was a blip. For this new job, I didn't list it either. I then have to call a third party background check firm for a short background interview. They basically asked about all my work history and other things pertinent to a background check. I fully disclosed all my jobs for the past five years, including the short-lived gym job. I told them why I didn't list it on any of my paperwork, since it was irrelevant to my work experience. 

Am I screwed? I didn't even think about it. Will it be seen as an intentional omission and disqualify me? I'm a little nervous for some reason. 

Thanks and sorry for the wall of text.
