The San Francisco 49ers will not be adding veteran safety Juan Thornhill to their secondary. The former Cleveland Browns defender visited the 49ers last Thursday but is signing with the Pittsburgh Steelers, per NFL Network's Ian Rapoport and Mike Garafolo.
The #Steelers are signing FA S Juan Thornhill to a 1-year deal, per me and @MikeGarafolo. An opportunity with one of the NFL's best defenses to show he's still a top safety. The former #Browns standout lands in a division he knows well. pic.twitter.com/hN0ikaXZOb

San Francisco has already made a couple of additions to its secondary by signing safeties Richie Grant and Jason Pinnock.
