The NBA released the list of 2012 combine invitees on Tuesday, and Ashton Gibbs' name was not on it. The combine will take place in Chicago on June 7-8, while the draft is on Thursday, June 28 at the Prudential Center in Newark, New Jersey.

Gibbs has already worked out for the Lakers and the Nets. Cardiac Hill considers his omission from the combine to be "at least a slight surprise." More from Cardiac Hill:

Gibbs recently participated (and fared well) in the Portsmouth Invitational. Plus, he's worked out for several teams, so all's not lost. Gibbs may have the opportunity for more workouts and the chances are good he'll end up on a summer league team as an undrafted free agent.

Still, as I recently wrote, it will be an uphill battle for him.
