Johnson had missed the team's previous two days of practice after injuring his ankle late in the Lions' game against the Green Bay Packers last Sunday.
While head coach Jim Caldwell refused to say Thursday whether Johnson would play in Sunday's game against the New York Jets, the receiver said Wednesday he was looking forward to facing the Jets' struggling secondary.
Johnson, 28, has 19 receptions for 329 yards and two touchdowns this season. Detroit is 2-1 entering Sunday's game at the Meadowlands.
