The Washington Redskins have released third-year linebacker Robert Henson, who had spent the last eight days of training camp practices on the team’s Physically Unable to Perform (PUP) list.

The Texas Christian product tweeted “Just got released later Redskin faithful it’s been real!!” In a following tweet, Henson thanked coach Mike Shanahan for the opportunity he’d been given.

Washington drafted Henson in the sixth round of the 2009 draft, and he appeared in two games as a rookie. The middle linebacker was the team’s leading tackler during the 2010 preseason, with 19 tackles and two sacks. But he suffered a season-ending knee surgery in the final preseason game and spent all of last year on injured reserve.

In fact, Henson was probably best known for his outspoken manner on Twitter. He often criticized fans whomhe didn’t consider supportive enough, and this spring questioned the organization’s decisions via Twitter.

The 6-foot, 247-pound Henson had yet to practice fully this season.

Washington has recently re-signed Rocky McIntosh and second-year LSU product Perry Riley, who are competing for the starting inside linebacker spot next to defensive captain London Fletcher.

The team also has interest in former Seattle linebacker Lofa Tatupu, who was released by his team last weekend. Tatupu was at Redskins Park on Thursday and had a physical, but left without a deal.
