Hey there EZRider, plants are actually really tenacious living beings, so any kind of "injury" usually they will be able to recover from . The problem is essentially contact with air and with light, the combination of these two things and a "cut" on the plant can lead to infection or actual oxidisation of the inside of the stem which prevents good healing. That's why growers make "bandages" using opaque tape like duct tape. but you have to catch it early, or basically instantly. Beyond that, there's nothing you can do except be patient and hope for the best. I'm sure it will be fine. Hope this helps ! ๐
