Gaba, who's battling cancer, announced the selection from the Ravens' Draft Fest on Saturday. Baltimore selected Oklahoma guard Ben Powers with the No. 123 pick.

According to ESPN, Gaba lost his sight when he was nine months old. The Ravens shared a heartwarming video on Wednesday featuring coach John Harbaugh surprising him with the invitation while Gaba was on with a local radio show.
