Something will be missing among the star power participating in Saturday's 10th edition of the Reebok Heroes Charity Baseball Game at Dr Pepper Ballpark in Frisco.

Dallas Stars sure-fire Hall of Famer Mike Modano, whose charity is a beneficiary of the event, will be there. Cowboys stars DeMarcus Ware and Bradie James will take the field. So will former Cowboys greats Drew Pearson and Everson Walls, as well as a variety of big- and small-screen actors.

Dallas Mavericks owner Mark Cuban and team president Donnie Nelson will also be there. Cuban, however, will leave his glove at home. He's on the shelf, rehabbing a torn rotator cuff (no surgery as of yet). Cuban will stay busy though, hanging in the stands with his newest best friend, the Larry O'Brien NBA championship trophy, and posing for pictures with fans.

So what's missing?

How about Cuban's world champs?

For the first time in at least the last five years of the Heroes game, no Dallas Mavericks players will participate. It's not official, but it certainly appears that the reason comes down to one nasty word: lockout.

The NBA forbids team executives and coaches from talking to players during the lockout, which took effect last Thursday night. For that reason, it appears, no Mavs players are on the roster with Cuban and Nelson out there (and possibly a David Stern spy drone flying overhead).

Last year, Jason Kidd played. James Singleton represented in 2009 with Jason Terry doing the honors in 2008 and Devin Harris in 2007. In 2006, Terry, Jerry Stackhouse and Marquis Daniels all hit the diamond.

Would the NBA really frown on Mavs players mingling with team brass at such a fan-friendly charity event? Well, it's hard to say. An NBA spokesman said he didn't know enough about the event to make a call. He did, however, mention that there are exceptions. For instance, Cuban and the Mavs will be together for the ESPY Awards in Los Angeles.

Miami Heat coaches were given the green light to attend Chris Bosh's wedding.

It would seem Cuban, Nelson and any Mavs players could play ball for charity without violating any lockout codes of silence.

But then, sillier things have happened.

So if you're headed to the game, congratulate Nelson on all his right roster moves, applaud Cuban for his postseason composure and encourage him to fight through his rotator cuff rehab. Take a picture with the trophy.

But barring a last-minute change, don't expect to get a glimpse of the world champs.
