The Raiders moved to address their shortcoming at cornerback by lining up visits with veterans Tracy Porter and Ron Bartell, according to reports.

Bartell, 30, and Porter, 25, have far more starting experience than any of the cornerbacks on the Raiders roster. Bartell started 65 games during his seven seasons with the St. Louis Rams, Porter 39 in his four seasons with the New Orleans Saints.

The Raiders are in the market for a proven cornerback on the heels of releasing seven-year pro Stanford Routt last month.

As of now, the Raiders have only three cornerbacks on their roster — second-year players Chimdi Chekwa and DeMarcus Van Dyke, as well as third-year player Brandon Underwood.

In other news, former Raiders defensive end Trevor Scott reportedly is slated to visit the New England Patriots.

Scott spent his first four NFL seasons with the Raiders, playing mostly defensive end. He also is versatile enough to play linebacker and help out on special teams.

Scott started 16 games for the Raiders, but none last season, when he recorded only seven tackles in 16 games.
