49ers waive Demarcus Dobbs, sign Chance Casey to practice squad

The San Francisco 49ers have waived defensive lineman Demarcus Dobbs. The 49ers have not announced the move, and there is no word yet on any corresponding transaction. The team signed cornerback Chance Casey to the practice squad, meaning they still have one roster spot open. Casey fills the practice squad spot vacated when Leon McFadden was signed to the 53-man roster.

The move is a little surprising, but not shocking. He was inactive this past Sunday against the St. Louis Rams, and all indications are that he was a healthy scratch. Tony Jerod-Eddie has been the primary backup along the defensive line, while Dobbs has gotten a decent amount of work there, and a lot of special teams work.

The 49ers will welcome back Glenn Dorsey sometime in the next couple weeks, and they also will activate Aldon Smith from suspension sometime between now and Week 11. I doubt that Smith will be activated this week, although I suppose we could hear something by the end of today. If Dorsey does not return this week, the team could be fine going with Quinton Dial for one more week as the backup after Tony Jerod-Eddie. Once Dorsey returns, he will likely work his way back into the mix with TJE, while Ian Williams remains at nose tackle.

Jim Harbaugh will meet with the media Wednesday afternoon, so I am sure he will get a question or two about this roster move.
