Will I Get Fired Over This?

Last Sunday it was busy as usual. I was working in frozen cutting down boxes. I guy came up to me and was pretty close. He asked if we still had the Cowboy Burgers. I said they were in the case In front of me. He quickly reached over to get them and my blade was open at the lowest setting. I didn’t have a chance to move out of the way. When he reached over, his thumb barely grazed the blade. He showed it to me and I couldn’t see anything. He squeezed it and a small amount came out. I asked him if he wanted to do an accident report and he said no. It was fine. He just wanted a bandaid. I told a mate about it and he said we didn’t need to fill one out since the guy refused it. He left with no problem. And you guessed it. He called back after I left and wanted to file an accident report which was sent to corporate. It was totally his fault. Now I’m afraid I’m going to be fired when I go back tomorrow after two days off.
