With their secondary battling injuries, the Pittsburgh Steelers added depth to the position Tuesday signing veteran cornerback Justin King, Ed Bouchette of the Post-Gazette is reporting.

According to Bouchette, King worked out for the Steelers (7-7) a few weeks ago. The former Penn State player will be asked to provided much-needed depth to the Pittsburgh secondary, which played without starting cornerback Ike Taylor (hairline fracture) and backup Cortez Allen in Sunday's 27-24 loss at the Dallas Cowboys.

The Steelers other starting cornerback Keenan Lewis (hip) left the loss with injury, and the Cowboys frequently exploited backup cornerback, Josh Victorian.

King, 25, was a fourth-round draft selection by the St. Louis Rams in 2008. This season, King played for the Indianapolis Colts before he was released in Week 5.

It's not expected that Taylor will return for the Steelers' remaining two games, while its still questionable if Allen will play Sunday against the visiting Cincinnati Bengals (1 p.m. ET on CBS).
