Cabral stated it was an "honour" to wear the ribbon after Wimbledon officials rejected his initial request to wear a black armband due to the tournament's strict all-white dress code.
Cabral described Jota as an "inspiration" not only for him but for Portugal as a whole.
British doubles player Neal Skupski, a Liverpool fan, also considered wearing a black armband but chose not to, though he may do so later in the Championships.
