Rowan tweeted that the six schools left on his list - in no particular order - are UCLA, St. John's, North Carolina, North Carolina State, Louisville and Wisconsin.
The 6-foot-7 Rowan confirmed to Scout.com later in the evening that the list is for "both" if he stays into the Class of 2016 or reclassifies and enrolls at a school in the Class of 2015.
Rowan has been pondering a decision to reclassify for several months and a final decision is likely to come in the next week.
Originally committed to Pittsburgh until the fall of 2014, U of L assistant coach Mike Balado was one of the first coaches to jump into the mix after he backed off the pledge. Balado and U of L coach Rick Pitino have been to watch him numerous times in a year and a half.
Louisville is the only official visit Rowan has made to date.
