Does this look like a bat bite?

Does this look like a bat bite? Husband and I were outside around 11pm in Indianapolis in a hotel parking lot. Husband was lifting heavy items, like an unboxed microwave, boxes, and an ironing board into another car. Husband was wearing a hoodie, jeans, and shoes. I saw bats flying around a distance away, nowhere near us. When we got inside, I found this mark on his hand. Husband says he neither saw a bat near him nor felt a bat touch his hand. I want to know if he would feel it and if this looks like a bite. It is one mark, not two puncture holes. Could it be a scrape from lifting things instead?
