I have a branch that I accidently broke, plz help

[Plaz]

First time grower of anything here. I have a sweet 100 plant, that in tying it up, I broke the branch. It is the bottom branch and I always thought it was too low (right at ground level) and it has no fruit, although it is a pretty large branch. Today it is wilted bad. What I need to know is how best to get it off the plant. It is still connected and I didn't know if I should cut it off or what? Also once it is off do I do anything with the injured part of the main stem?

Thanks!
