Former Dallas Cowboys cornerback Sterling Moore, who visited with the San Francisco 49ers on Wednesday, has agreed to sign with the Tampa Bay Buccaneers.

The 49ers lost 2014 starting cornerbacks Chris Culliver (Washington) and Perrish Cox (Tennessee), but brought in Shareece Wright from the Chargers and re-signed Chris Cook.

With free agent options shrinking, cornerback remains one of the 49ers' biggest needs heading into the NFL Draft.
