The San Francisco 49ers signed former San Diego Chargers cornerback Shareece Wright to a one-year, $3 million deal. The contract is worth up to $4 million. The 49ers lost Chris Culliver (Washington Redskins) and Perrish Cox (Tennessee Titans) in free agency. Wright, 28, has started 27 games for the Chargers for the past two years. He's a former third-round pick in 2011. Wright has a league-high eight pass interference penalties last season.
