The Washington Redskins added another piece to their secondary, agreeing to terms on a one-year deal with cornerback Cedric Griffin, a person with knowledge of the situation confirmed Friday.

Griffin, a six-year veteran, drafted 48th overall out of Texas by the Minnesota Vikings in 2006, will sign a contract that will pay him up to $2.5 million, the source said.

Griffin agreed to terms during a visit to Redskins Park on Friday.

The 6-foot, 203-pounder last season started 14 of 16 games, recording 67 tackles, nine pass breakups and one interception. Griffin tore an ACL in January 2010 while playing in the NFC championship. He recovered in time to play by Week 3 of the 2010 season, but then tore his ACL in the other knee. He returned as a starter in 2011, but wasn’t quite the same, and was replaced in the lineup for the final two games of the season. The Vikings released him earlier this week, saving $5.2 million against their salary cap.

Before releasing Griffin, the Vikings reportedly had considered moving him to safety. In addition to a third corner, the Redskins were expected to add a free safety following Monday’s release of Oshiomogho Atogwe.

Griffin wasn’t the only free agent cornerback at Redskins Park. Former New York Giant Aaron Ross arrived in Ashburn after flying in from Cincinnati, where he met with the Bengals on Thursday.

The 6-foot, 190-pound Ross has spent his entire five-year career with the New York Giants. Last season, he started 15 out of 16 games, recording 60 tackles and four interceptions to go with 12 pass breakups.

As of early Friday afternoon, he had yet to agree to terms with the Redskins.
