Johnson (ankle) did not practice Friday and is listed as doubtful for Sunday's game against Denver, Brianna Dix of the Buccaneers' official site reports.
Johnson opened the week as a limited participant in Wednesday's practice, but he was a DNP Thursday and Friday, and he is not expected to play Sunday. The Bucs could call up a wide receiver from the practice squad such as Sterling Shepard, Cody Thompson or Ryan Miller in anticipation of Johnson being inactive for Week 3.
