Coach Jim Schwartz had said his "special" target would be a game-time decision Sunday against the Seahawks. He is active for the first time since he injured his right knee on Oct. 11 against Pittsburgh.
Johnson has 20 catches of 25-plus yards the last two seasons, second most in the NFL. The 6-foot-5 receiver has a huge size advantage on Seattle's smallish secondary.
Starting defensive tackle Grady Jackson was inactive for the first time this season. Detroit had listed him as probable with a knee injury, though he did not practice Thursday or Friday.
Seattle was relatively healthy, given it's had 12 starters miss at least one game to injury.
