In English I can write "A versus B" "A vs B" or "A vs. B".
Can I do the same in Spanish?
Also, English word "versus" is "versus" in Spanish?
Spanish rules state that the correct abbreviation is
vs. and not
as sometimes it is seen.
From RAE you can read that it comes from latin and initially meant "towards" (hacia in Spanish) but later got the meaning of against (contra).
It means and it is spelled in the same way both in Spanish and English.
In Spanish it is widely used in writing especially on sports but as guifa pointed out in his comment when speaking we usually say "contra" or "frente a".
RAE is not the same as Oxford. RAE provides rules in order to unify the Spanish spoken worldwide. You can read about it in the Wikipedia: https://es.wikipedia.org/wiki/Real_Academia_Espa%C3%B1ola
Now, answering your question, the right way to abbreviate versus in Spanish is vs. http://buscon.rae.es/dpd/apendices/apendice2.html
