pulled early root out

Ok, so i was wondering i germinated seeds a few days ago using the paper towel method. After a few days, i planted the seeds and they have sprouted and i see 2 leaves with 2 more about to come out. I moved a little piece of the root and it felt loose. So, i picked it up and just re-planted it in the soil with both of them. Will this kill the plants or is it fine they are about 5-7 days old now.
