Johnson, who has criticized the NFLPA regarding supplement use, will be eligible to return to the Eagles' active roster on Monday, December 19 following the team's December 18 game against the Baltimore Ravens.
The next game following that will be on December 22nd against the New York Giants.
Johnson was suspended for four games in 2014 after he tested positive for a banned substance. Johnson said he had taken a prescribed medication without checking with the Eagles' medical staff.
