The Jets have signed linebacker Tim Fugger to the practice squad to replace Lansanah.
Lansanah had a decent preseason as a backup inside linebacker, but more importantly on the special teams coverage units, where the Jets are struggling for bodies with Garrett McIntyre out, Troy Davis and Antwan Barnes on injured reserve and Ricky Sapp gone. The injuries to Konrad Reuland and Josh Cribbs didn't help in this regard either and the Jets had to play the likes of David Harris, Caleb Schlauderaff and Dawan Landry in unfamiliar roles on Sunday to make up for this.
However, when a player is acquired from another team's practice squad, it's generally protocol for that player to approach the existing team to see if they will activate that player themselves and the fact they didn't perhaps isn't surprising because adding a 28-year old to the active roster would be more of a short term move. Also, he has the same agent as Ryan Spadola, who you'll recall didn't even realize the Jets would have re-signed him until he was already in Miami, so maybe the Jets weren't even given this option.
Lansanah is guaranteed to be on the Bucs roster for at least three games, so this pretty much ensures he'll remain there until the end of the season so they can retain his rights.
