This is a new thing for NBA teams to have a farm team as an option to get injured players practices/workouts in. The Spurs had Tony Parker down with their GLeague team earlier this season to get ready. Usually they won't play in a game. It's to practice with the GLeague team, get full court run, get into game shape. This is basically September for Parker right now, so you're looking at him being at least 4 weeks away from getting into a game with the Bucks.
