CHICAGO -- Chicago Bears general manager Phil Emery said Sunday he would continue looking to bolster the team’s roster during the season.

“If I’m up later than I should be, it’s because I’m studying who’s available out there and can add to the Bears and continue to work on our roster,” Emery said on WBBM-780 AM. “As I’ve said on numerous occasions, we can’t rest on our roster.

“Is there room to be creative (with the salary cap)? There’s always room to be creative to make things happen. … There is room. We’ll just have to do it step by step.”

Emery stayed busy this past offseason. Among his moves were trading for wide receiver Brandon Marshall and cornerback Sherrick McManis and signing running back Michael Bush, quarterback Jason Campbell, linebacker Blake Costanzo, cornerback Kelvin Hayden, linebacker Geno Hayes, defensive end Cheta Ozougwu, guard Chilo Rachal and wide receiver Eric Weems. He also signed running back Matt Forte to a new contract.

Emery said he preferred not to renegotiate players’ contracts during the season. But if he did, he said they would be done privately. Linebacker Brian Urlacher is among the Bears in their final contract season.
