ASHBURN, Va. -- Defensive end Jason Hatcher is impressing some of the Washington Redskins he once depressed.

Outside linebacker Ryan Kerrigan, for one, thinks the addition of Hatcher is a key this year for the Redskins.

"Jason Hatcher looked great out there," Kerrigan said, referring to Saturday's preseason game against the Baltimore Ravens. "He's the same guy who terrorized us when he was with Dallas. I thought we worked really well together and put a lot of pressure on their quarterbacks."

Hatcher, who sat out the first two preseason games as he completed his rehab from arthroscopic knee surgery performed in June, ended the Ravens' second series with a sack of quarterback Joe Flacco.

It was the only tackle with which the 32-year-old former Cowboy was credited, leaving coach Jay Gruden wanting to see more from a player whose 11 sacks in 2013 were more than double his previous career high.

"It was good to see him out there in a first game experience with us," Gruden said. "(However,) he has to get in playing shape. I could see that he was a little winded out there.

"I think he's a great addition to our football team. We just have to make sure that we work his butt off the next couple of weeks to get him ready for (the Sept. 7 regular-season opener at) Houston."

The release of outside linebacker Rob Jackson on Sunday left receiver Santana Moss -- acquired in a March 2005 trade -- and defensive end Kedric Golston -- a sixth-round draft choice in 2006 -- as the only players on Washington's roster who were with the team when the Redskins started 6-2 under then-coach Jim Zorn in 2008.

Jackson, a seventh-rounder in 2008, got into just 10 games during his first three seasons and played mostly on special teams in 2011 before becoming a solid starter in 2012 after Pro Bowl pick Brian Orakpo sustained a season-ending torn pectoral muscle in Week 2. It was Jackson's late interception of Dallas quarterback Tony Romo in the Week 17, winner-take-all game against the Cowboys that sealed Washington's first and only division title this century.

However, with Orakpo healthy again last year, Jackson didn't see much action last season. Jackson also missed the first four games in 2013 while serving a suspension after a positive drug test.

Aside from Moss and Golston, cornerback DeAngelo Hall (waivers, November 2008) and 2009 first-rounder Orakpo are now the only remaining Redskins who pre-date former coach Mike Shanahan's 2010 arrival.

--With the Redskins signing free agent wide receivers DeSean Jackson and Andre Roberts and drafting receiver Ryan Grant, the odds of 2013 undrafted rookie receiver Nick Williams making Washington's roster seemed pretty slim when training camp began.

However, Williams caught a touchdown pass in the fourth quarter for the second consecutive preseason game Saturday. This one wasn't a game-winner as was the case five days earlier against the Cleveland Browns, but it did draw the Redskins within 23-17 with 5:03 to play.

"Nick really studies the position and he carries himself as a professional, and I'm happy to see the fruition, in terms of the touchdowns, the last two weeks," said backup quarterback Kirk Cousins, who hit Williams with the 7-yard strike against the Ravens. "He's a good receiver who can help us."

The Redskins have seven touchdowns this summer, and Williams is the only player with more than one. Jackson, Roberts, 2013 record-setter Pierre Garcon, former starter Moss and Grant appear to be locks to make the team. However, if Washington keeps a sixth receiver, Williams just might beat out speedster Aldrick Robinson.

"(Nick)'s good because he can play multiple spots," Gruden said. "(He's) very smart, very reliable, a very defined route runner. He's got good hands. He's just another guy that has performed well. It will be a difficult choice when it comes to choosing the receivers. Nick ... can play in the NFL, there's no doubt about it, and hopefully it's for us."
