The Redskins continue to add and subtract pieces, waiving tight end Dominique Byrd, and signing cornerback Domonique Johnson, a person with knowledge confirmed.

 Byrd joined the team only two weeks ago. He suited up for last Sunday’s game, but didn’t play.

 Johnson, a 6-foot-2, 198-pound Jackson State product went undrafted in 2009 but signed with Denver as a free agent. He has had brief stints with the Broncos and the Giants during his career, appearing in five games on special teams.

The Washington Redskins have waived backup defensive lineman Darrion Scott and signed free agent defensive end Kentwan Balmer, according to a person with knowledge of the situation.

Scott, who had been inactive for all eight of Washington’s games this season tweeted, “Would’ve liked to stay but it wasn’t meant to be. #Redskins”

The Ohio State product appeared in two games for Washington last season and spent four seasons (2004-2007) with the Minnesota Vikings, recording 130 tackles and 9.5 sacks in a total of 48 games.

Balmer, selected with the 29th pick of the 2008 draft by the San Francisco 49ers, was without a team and hasn’t played since last season, when he suited up for 16 games with the Carolina Panthers, starting 11 of them. He recorded 43 tackles. He spent two previous seasons with the 49ers but did not start, registering 19 tackles in 28 games.

A 6-foot-5, 315-pound North Carolina product, Balmer will compete for playing time behind veteran defensive linemen Adam Carriker, Stephen Bowen and Kedric Golston.
