The veteran quarterback signed with the Chicago Bears last season, though he did not appear in a game during the 2017 season. On April 13, 2018, he was suspended for four games for violating the NFL's performance-enhancing drug policy. Sanchez tested positive for performance-enhancing drugs while a free agent and cited "unknowing supplement contamination" in his statement to the media following the suspension.
Sanchez has appeared in 77 career regular season NFL games, throwing for 15,219 yards. He has a 56.7 career completion percentage, 86 career touchdowns and 86 career interceptions.
Oddly, his first game as a Redskin will be the sixth-year anniversary of the "butt fumble."
