Brad Biggs of the Chicago Tribune cleared the air via Twitter:
Don't believe Twitter speculation #Bears signed Anthony Hargrove is accurate.
Meanwhile, Mike Triplett of the Times-Pic also says no signing has happened, but that both parties are in talks:
@MikeTripletttp just told our night editor that talks of #Saints' Hargrove signing are premature, he and #Bears are still in talks.
Stay tuned for further details.
