Does Brady have 3 broken ribs?

According to Charley Casserly on the NFL Today, Tom Brady has 3 broken ribs. He does not expect him to play longer than 1 or 2 series against the Texans.

If this is true how significant are these injuries? Tom Brady has still been able to throw the ball down the field. I haven't seen a huge drop off in his accuracy since this injury during the Dolphins game. This injury came over 3 weeks ago.

Charley is a former GM and usually has very good information. I don't doubt the story, but would he playing if the ribs were severely broken? Why would the Patriots risk playing him at all this week? My feeling is he is not as hurt as being reported.
