Oakland was apparently impressed with Haskins' workout and could potentially take him with the No. 4 pick, Rapoport added.
The Raiders' three first-round draft selections have been attached to numerous rumors this offseason. It was reported in March that head coach Jon Gruden was very interested in Kyler Murray, who, along with Haskins, is expected to be drafted in the first round.
General manager Mike Mayock stated in February, however, that he believes Derek Carr is capable of being a franchise quarterback.
Along with the fourth overall selection, the Raiders also hold the No. 24 and No. 27 picks.
