The Broncos designated Johnson (hamstring) for return from injured reserve Wednesday, Aric DiLalla of the team's official site reports.
Johnson hasn't played since Week 7 due to the hamstring injury, but he at least looks as though he'll be ready to practice this week. The Broncos will have 21 days to evaluate Johnson before either adding him back to the 53-man roster or keeping him on IR for the remainder of the season. Johnson recorded eight receptions for 122 yards and three touchdowns on 13 targets through Denver's first seven games of the season.
