The Lions made a pair of roster moves tonight, signing free agent linebacker Bobby Carpenter and signing cornerback Paul Pratt back to the practice squad.
Carpenter worked out for the Lions earlier today. If you're not familiar with him, here is a quick look at his NFL career from my post over at SB Nation Detroit:
Carpenter was just released by the Dolphins earlier this week. He joined Miami in early September after being let go by the Rams during the final round of roster cuts. He ended up in St. Louis after the Cowboys traded him. Dallas originally drafted him with the 18th overall pick in 2006.
As for Pratt, he spent a couple days on the 53-man roster before being demoted back to the practice squad. He was added to the 53-man roster before Sunday's game, released and now has been added back to the practice squad. Basically, the Lions were able to play him in an actual game by calling him up, and they have essentially sent him back down to the practice squad now; he just had to be released to make the move back down possible.
