Here is an updated (and unofficial) list of those who are playing and also those who have taken a pass on this week's NBA Pre-Draft Camp in Orlando:

The headline names of those who FOXSports.com has confirmed will be participating include the North Carolina duo of Wayne Ellington and Danny Green, Memphis big man Joey Dorsey and a trio of players from the national champion Kansas Jayhawks - Russell Robinson, Darnell Jackson and Sasha Kaun.

Kansas' Darrell Arthur, Mario Chalmers and Brandon Rush, DeAndre Jordan (Texas A&M), Russell Westbrook (UCLA), Rider's Jason Thompson, Nevada's JaVelle McGee Syracuse's Donte Greene and Joe Alexander (West Virginia) will take a pass on playing in the event in fear of hurting their stock. Ditto for Chris Douglas-Roberts, D.J. White, J.J. Hickson, Chase Budinger, Courtney Lee and Bill Walker.

Obviously, guys like Michael Beasley, Derrick Rose, Brook Lopez, Jerryd Bayless, Kevin Love, O.J. Mayo, Eric Gordon, D.J. Augustin and Anthony Randolph will be among those invited down as physical-only players.
