Jones Back To Colorado, Greenspan To Charlotte

Steven Goff tweeted this afternoon that Jermaine Jones was heading back to Colorado after having his knee looked at by the National Team doctors and not being cleared to play.  Its the right move, I just don't understand why he was "called up" if it was really just about getting a second opinion on his knee.  Why not just announce that and avoid the bad optics?

Also the Independence announced that Joseph Greenspan is heading to Charlotte on loan.  As expected the load to the Switchbacks didn't last all season, I'm just surprised he's not staying in Denver.  I wonder if he's filling a roster gap left by the recall of Calvert (or possibly Berner if he was called back to back up MacMath this weekend).
