Tweet Tweet: Rondo's rehab update

It's not much, but having been mum most of the summer about his rehab from ACL surgery, Rajon Rondo offered a tiny update during a Twitter Q&A with his followers on Wednesday night:

On Tuesday, Celtics president of basketball operations Danny Ainge said that he would be "shocked" if Rondo was ready for opening night and suggested a possible December return for the All-Star point guard. Rondo is back in Boston now to continue his rehab. The Celtics open training camp next week in Newport, R.I.
