"He was a little bit sore. It would be great if he could be available to us on Sunday," said Sherman. "I should avoid saying that he's gonna play, but we're hopeful that he can play. We'll evaluate that more on Sunday."
Rossum is listed as questionable on the injury report, meaning he has a 50 percent chance of playing.
The Packers are among the worst punt and kickoff return teams in the league, ranking 30th on punt returns and 31st on kickoff returns.
Herbert "Whisper" Goodman and Dorsey Levens are expected to return kickoffs against the Titans. If Rossum is not ready to play, the Packers could use either Robert Ferguson, Charles Lee, Donald Driver, Antonio Freeman or Darren Sharper to return punts. Ferguson sat out last Sunday's game against Chicago because he strained his hamstring in practice a few days before the game.
The Packers could be without three of their starters on defense. Linebacker Nate Wayne, nose tackle Gilbert Brown and defensive end John Thierry did not practice Friday.
Wayne will be out at least two games after breaking a bone in his lower back against the Bears. Thierry sprained his right knee Dec. 3 against Jacksonville. Brown missed Sunday's game against Chicago because of turf toe. He practiced on Thursday and made it through the entire practice, but was in the training room today during practice.
Sherman said it will be a game-time decision regarding Thierry and Brown. If they cannot play, Cletidus Hunt will start for Thierry and Jim Flanigan for Brown.
