Last weekend, Lions linebacker Caleb Campbell was signed off the practice squad to the 53-man roster. On Sunday, he was active for the Lions' game against the Cowboys. He didn't actually play according to the game summary, but he was in uniform for a game for the first time in his career.
↵On Tuesday, the Lions decided to release Campbell with the intention of re-signing him to the practice squad. The reason for the move was that they signed offensive guard Donald Thomas to add depth to the offensive line with both Stephen Peterman and Dylan Gandy dealing with injuries.
↵Thomas is in his third year in the NFL and previously played for the Dolphins. He started 12 games in 2009 after spending his rookie season on injured reserve. This past September, the Dolphins released him in the final round of roster cuts.
↵The move to release Campbell and sign Thomas has already been announced, but nothing has been confirmed yet about Campbell being re-signed to the practice squad. I would be pretty surprised if another team claimed him off waivers, though, so I doubt there will be any issues with getting him back to the practice squad.
