The free agent safety market has started to thin, but several accomplished players remain available. Among them: Lions free agent Louis Delmas, who will visit the 49ers, ESPN’s Adam Schefter said Wednesday night.

The 25-year-old Delmas, a 49-game starter for Detroit in the last four seasons, visited St. Louis to begin free agency. Now he will be hosted by the Rams’ division rivals, who have a clear need in the defensive backfield with free safety Dashon Goldson moving on to Tampa Bay.

Delmas, ranked No. 49 on PFT’s Free Agent Hot 100, would be a solid replacement for Goldson on his best form. The primary potential concern with Delmas is durability. He missed eight games in 2012 and five in 2011 because of injuries to both knees.

The Lions added Texans free safety Glover Quin on Wednesday, filling one starting spot at the position.
