The 49ers can check Louis Delmas off their list of candidates to replace Dashon Goldson at safety.
Delmas, 25, has reportedly re-signed with the Detroit Lions, who gave their 2009 second-round draft pick a new two year contract.
The 49ers visited with former Green Bay Packers safety Charles Woodson on Wednesday in Santa Clara. Woodson has expressed interest in returning to the Bay Area - he played his first eight seasons in Oakland - to play with a Super Bowl contender.
Baltimore Ravens free agent safety Ed Reed is also available. Reed visited with the Houston Texans for two days, but left the team's headquarters today without a contract.
