RICHMOND -- As Trent Williams continues to hold out from Redskins' training camp, Washington has signed another veteran offensive tackle.

Veteran offensive tackle Donald Penn is flying to Washington, D.C. on Tuesday, and the Redskins plan to sign the veteran on Wednesday, according to NFL Network's Ian Rapoport.

Penn flew to Richmond last week for a visit with the Redskins, but left unsigned. The team signed offensive tackle Corey Robinson last week as well.

A three-time Pro Bowler, Penn, will bring much-needed depth at the tackle position as Williams continues to hold out from training camp.

The 36-year-old spent the past five seasons with the Oakland Raiders, but missed 12 games in 2018 due to a groin injury.
