Johnson brought in three of five targets for 12 yards and rushed twice for 13 yards in the Buccaneers' 24-14 preseason win over the Dolphins on Friday night.
The Barton College product overcame a multi-week rib injury just in time to participate in the final preseason game, and while he didn't do anything spectacular with his touches, Johnson was kept busy during his time in the game. The undrafted rookie had impressed throughout the offseason and early in training camp, so he may have a good shot at sticking on the practice squad come final cutdowns.
