Cobb, entering his fourth NFL season, was the team's primary return man in 2011 and 2012, averaging 26.3 yards on kickoffs and 10.3 yards on punts. The Packers limited his use on special teams last season after he had 954 receiving yards and eight touchdowns in 2012.
Packers special teams coach Shawn Slocum said the Packers have been planning to use Cobb on returns.
"He's been there all along," Slocum said. "We'll have him and Micah (Hyde) in punt return and we'll have DuJuan (Harris) and Micah as kickoff returners and Jeff Janis, as well."
Cobb missed ten games last season with a broken leg before returning for the season-finale and playoffs.
The Packers open the regular season on Thursday at the Seattle Seahawks.
