As the Packers prepare to face the 49ers in Sunday's regular-season opener, Green Bay will have a potentially valuable insider in the meeting room.

Scott Tolzien, a reserve quarterback cut by the 49ers last week, will be added to the Packers' practice squad, a source told Packer Report. The former Wisconsin standout will serve as the third quarterback behind Aaron Rodgers and B.J. Coleman.

Tolzien spent all of last season with the 49ers but did not enter a game. Praised by coach Jim Harbaugh for his work ethic and smarts, he opened this preseason with a shot at the No. 2 job behind Colin Kaepernick.

Instead, the emergence of Colt McCoy and rookie B.J. Daniels made him expendable. Now, Tolzien heads back to Wisconsin -- complete with an understanding of the 49ers' playbook.

The Sacramento Bee noted that there are only so many secrets Tolzien could divulge: The 49ers coaching staff had yet to unveil the game plan for the Packers and probably won't do so until Tuesday's practice.

  • Several other players cut by the 49ers found new homes Sunday. Receiver Ricardo Lockette tweeted "Proud to be a Chicago Bear!" after winding up on that team's practice squad.

    Receiver Chad Hall was claimed off waivers by the Kansas City Chiefs, according to ESPN contributor Adam Kaplan. The Bee reported that the Chiefs also claimed cornerback Marcus Cooper, adding to Kansas City's growing stable of former 49ers.

    Tight end MarQueis Gray was claimed off waivers by the Browns and will join Cleveland's 53-man roster. He wrote on Twitter: "Well it's been fun SF and thanks for all the love & support! Just got the word and now off to Cleveland to start over! Here we go Browns."

  • Seven of the 49ers' eight spots on the practice squad are accounted for, according to multiple reports. The list is shaping up as defensive lineman Mike Purcell, guard Patrick Omameh, running back Jewel Hampton, receiver Chuck Jacobs, tackle Carter Bykowski, safety Mike Thomas and cornerback Darryl Morris.
