The Raiders have signed Shareece Wright to a one-year deal. The cornerback personally announced the news on his Instagram account and the deal has been confirmed by Michael Gehlken of the Review Journal (on Twitter). 
Wright will serve as cornerback depth in Oakland. There, he’ll reunite with safety Marcus Gilchrist, who signed with the Raiders this week. Both players were in the same Chargers draft class in 2011 and spent four years together.
Wright appeared in 12 games for the Bills last season and started in five of those contests. He finished out with 42 tackles, one interception, and five passes defensed.
