Ravens coach John Harbaugh says he isn't sure if wide receivers T.J. Houshmandzadeh and Donte Stallworth will remain with the team.
"You can't really put a percentage basis on it because there are so many things up in the air at this time," Harbaugh said of the chance the receivers will return.
"There are obviously a lot of issues that haven't been a part of the equation in the past. It's just a different calendar now with free agency."
Houshmandzadeh, 33, and Stallworth, 30, each signed one-year contracts with Baltimore last offseason.
