Rodrigue has posted a summary article in The Athletic (Placing Marty Hurney's comments in context)
Some folks in this thread have talked about divorcing Rhule from that topic. This makes clear that Rhule was indeed part of the decision making process, though not part of the discussion with Newton when they told him their intentions.
As has been said elsewhere, extension talks are "expected to begin soon" but the Panthers aren't going to talk about it.
It's not stated that the Panthers are completely giving up on Little possibly playing left tackle in the future (Hurney sure isn't) but it doesn't sound like that's in the cards right now.
