The 49ers lost one of their cornerback starters, Perrish Cox, on Saturday but signed two others with starting experience, Shareece Wright and Chris Cook, to one-year deals.
Wright, 27, started 27 games in the past two seasons for the Chargers but has just one interception over that span. The 5-11, 182-pound Wright also is capable of playing nickel cornerback but mostly has been on the outside for the Chargers.
Cook, meanwhile, spent the 2014 season with the 49ers. The big-bodied 28-year-old cornerback mostly was limited to special teams before a hamstring tear ended his season in Week 7. Cook started 29 regular-season games the previous four years with Minnesota. He still is looking for his first NFL interception.
Cox, 28, had visited Washington and Cleveland prior to his trip to Tennessee. His departure followed that of Chris Culliver, who signed a multi-year deal with Washington earlier in the week.
It marks the second straight season both San Francisco starters at cornerback departed at the same time. Last year, Carlos Rogers and Tarell Brown signed with the Raiders. Both are free agents this year as well.
One of the 49ers’ starters this year figures to be Tramaine Brock, a Week 1 starter a year ago who suffered turf toe in the opener and never was healthy the rest of the year. Others in the mix include Cook, Wright and 2014 rookies Dontae Johnson, Keith Reaser and Kenneth Acker.
Cox, who led the team with five interceptions a year ago, started 14 games and played nickel cornerback for big chunks of the season as well. The nickel job likely will belong to Jimmie Ward in 2015 with Johnson and perhaps Wright also available.
