ASHBURN, Va. — The Washington Redskins have shored up their offensive line by re-signing swing tackle Ty Nsekhe and interior lineman Tony Bergstrom and exercising the fifth-year option on starting right guard Brandon Scherff's contract.

The Redskins announced the deals Monday as they began their off-season program. The signings ensure depth along the line for at least next season.

A two-time Pro Bowl selection, Scherff is now signed through 2019. Washington's first-round pick in 2015 has started 46 regular-season games and one playoff game.

Nsekhe, who was a restricted free agent, started five games at left tackle in place of injured Pro Bowl lineman Trent Williams last season. The 32-year-old has appeared in 42 games and started 11.

Bergstrom joined the Redskins last season, starting three games and appearing in nine after starting with Baltimore.
