This has not been confirmed by any other media source yet. Rumors are common in the hours leading up to the draft.
Update: Adam Schefter of NFL Network has reported that this rumor is false and that no trade has taken place and that the Broncos and Texans have not had a single serious discussion about swapping picks. Schefter also says that the Broncos would never do a deal like this before the draft. (From ProFootballTalk.com)
