Potentially, yes, assuming he meets the following criteria based upon his "felonious assault" (one of the enumerated "qualifying criminal activities" from which he became a victim) under the applicable statute: He is a person who (1) has suffered substantial physical or mental abuse as a result of having been a victim of the qualifying criminal activity; (2) possesses credible and reliable information establishing that he has knowledge of the details concerning the qualifying criminal activity on which his petition is based; (3) has been helpful, is being helpful, or is likely to be helpful to a certifying agency in the investigation or prosecution of the qualifying criminal activity; and (4) the qualifying criminal activity occurred in the US. One of the most difficult aspects relating to obtaining a U visa is actually getting a/the law enforcement entity to accede to being the certifying agency for such purposes. You should consult directly with the law enforcement authorities having current jurisdiction over your friend's assault case for further information and probabilities of certification.
