he's supposed to be out for game 5. if the bulls win that, I think it's safe to say they sit Rondo for game 6 to give the hand more time to heal if a game 7 is needed. if the C's win game 5, they'll probably push for Rondo to provide some limited minutes if at all possible.
would do as someone above suggested -- back off him and make him shoot. off course the problem with that is if IT is guarding him, he'll just have more room to make passes to cutters and open teammates like he did in the first 2 games.
