According Chris Russel of 106.7 The Fan, Albert Haynesworth will attend training camp if he is still part of the team by then, but I can't imagine this situation gets that far before its resolved. His goal is to avoid the potential fine he could be levied if he stays home.
If Albert were to miss training camp, the team may be able to re-coup some of the money from Albert's singing bonus. By attending the camp, he can't be fined, and the team will probably be unable to re-coup any portion of his enormous signing bonus. He didn't really earn all this money, but he seems intent on keeping it.
