By now, many of you have seen the Instagram photos. Starting Tuesday, various Mavericks players publicly shared initially-mysterious photos of themselves traveling to, then arriving in Miami.

Now we've been informed of what exactly is going on: At least eight Mavericks players, and likely more, have rented a gym in Miami for three days of training and bonding.

For the most part, it's a players-only thing: I'm told the franchise did send a skeleton crew of assistant coaches and trainers to be present during the workouts. Mind you, training camp doesn't begin until Oct. 1, but Mavericks players obviously decided to get a head start.

As you can see in this photo Kristaps Porzingis shared Wednesday night on Instagram, he at the very least has been joined in Miami by (L-R) Luka Doncic, Isaiah Roby, Jalen Brunson, Dwight Powell, Justin Jackson, Dorian Finney-Smith, Tim Hardaway Jr. and Delon Wright.

Then there is the matter of who took this photo. Had to be someone tall, judging from the camera angle. Most likely not J.J. Barea.

We know free agent signee Seth Curry is not with the group, or if he is he's got some serious explaining to do to Callie Rivers (daughter of Doc), whom he's scheduled to marry today.

And we know Boban Marjanovic is in China, somewhat busy today helping Serbia defeat the United States in the FIBA World Cup -- and in the process toying with Donovan Mitchell like a rag doll.

I’m told most of the Mavericks players who are in Miami are scheduled to return Friday. Doncic has committed to take part in ex-teammate Dirk Nowitzki’s Pro-Celebrity Tennis event Sunday at SMU.
