The Buccaneers signed veteran defensive end Darryl Tapp after a workout on Tuesday and they revealed the reason for their interest in defensive line help on Wednesday. The Bucs announced that defensive end Noah Spence has been placed on injured reserve. Spence has a shoulder injury that has hampered him for much of the season and recorded one sack in six games. He had 5.5 during his rookie season in 2016, but also dealt with shoulder issues that year so finding a permanent solution to the problem would be a good way to head into his third NFL season.
