The Lions have signed defensive end George Johnson. To make room, Detroit has waived fellow defensive lineman Alex Barrett. 
Johnson spent the 2014 season with the Lions, a campaign sandwiched by his two stints with the Buccaneers. He was quietly effective in that season, appearing in all 16 games and earning a positive grade from Pro Football Focus. The Lions are hoping that he can still be an effective pass rusher in 2017.
Johnson’s second stint with the Bucs came to an end earlier this month when he missed the 53-man cutdown. Tampa Bay saved $2.25MM by terminating his deal in advance of Week 1.
In the process, the Bucs get themselves off the hook for his $2.25MM salary, which would have become guaranteed if he was on the roster for Week 1.
Unfortunately, Johnson hasn’t seen the field since the 2015 season. Last August, an ACL tear shut him down for the year.
