Updating a previous item, the 49ers will not be signing free agent Daunte Culpepper right now, a source tells ProFootballTalk.com.
According to PFT's source, the signing still could happen in the next week or so if Culpepper isn't scooped up by another team. It's unclear why the Niners suddenly backed off the 34-year-old, but maybe he thinks he can reach higher on the depth chart. San Francisco was only offering the third-string gig behind Alex Smith and Colin Kaepernick.
