Chaisson (knee) was a full participant in Wednesday's practice, Zach Selby of the Commanders' official site reports.
Analysis:Chaisson suffered a knee injury during a joint practice with the Dolphins in early August. The linebacker sat out all three preseason games but has recovered from the injury at the perfect time. The 27-year-old is all set to suit up for the Sept. 13 regular-season opener against the Eagles.
