In what represents their most notable acquisition of outside talent since Tuesday’s free agency period began, the Redskins have reached an agreement Thursday evening with former Dallas Cowboys defensive lineman Jason Hatcher, according to his agent and a person within the Redskins organization.

Terms of the deal weren’t immediately available.

Hatcher last season led the Cowboys with 11 sacks, which is more than Washington’s defensive linemen combined, and one more than outside linebacker Brian Orakpo tallied in 2013.

The 6-foot-6, 299-pound Hatcher, who will turn 32, has seen his production increase in each of the past three seasons. He spent the first five seasons of his career as a backup before breaking into the starting lineup in 2011. He had lined up at right defensive end in Dallas’ 3-4 front before switching to defensive tackle when the Cowboys went with a 4-3 front this past season.

His acquisition further puts in doubt the future of defensive end Stephen Bowen, who is coming off of microfracture surgery and has a cap hit of just more than $7 million.

He had visited both the Seattle Seahawks and Oakland Raiders and was scheduled to visit Washington on Friday, but the Redskins pulled off a deal with him in advance of his trip to the area.

Hatcher is expected to help upgrade a defensive front that struggled to generate pressure last season. That could in turn help improve the effectiveness of Washington’s secondary.
