GREEN BAY, Wis. -- Ahmad Brooks won't be the only addition the Green Bay Packers will have on their defense.

They picked up another potential pass-rusher Sunday when they claimed rookie Chris Odom off waivers from the Atlanta Falcons. It means they will have to make two roster moves to clear the way for the newest players.

Brooks, the former San Francisco 49ers outside linebacker who agreed to terms last week, will officially sign either Sunday or Monday.

Even with Brooks unofficially in the fold, the Packers still kept 53 players on their initial roster after Saturday's final roster cuts. Any player whom they would want to go on short-term injured reserve (and be one of the two IR players who are eligible to return at some point this season) needed to be on the roster at final cuts, so perhaps one of the two newcomers will get a roster spot that way.

There's a good chance third-round defensive tackle Montravius Adams, who had foot surgery after two days of training camp practices, will end up on injured reserve. The other roster spot likely opened when the Packers traded outside linebacker Jayrone Elliott to the Dallas Cowboys on Sunday, according to a report from ESPN's Todd Archer, who said the Packers got a conditional seventh-round draft pick in return.

Odom, 6-foot-4 and 256 pounds, had two sacks this preseason for the Falcons, who signed him as an undrafted free agent from Arkansas State. He had 15.5 sacks in his college career, and 12.5 of those came last season.

Odom was the Packers' only waiver claim, but two of the players they cut on Saturday were picked up -- quarterback Taysom Hill by the New Orleans Saints and defensive tackle Brian Price by the Cowboys.
