The Baltimore Ravens are expected to sign Griff Whalen on Thursday to help their banged-up wide receivers, according to a source. The Ravens' top three receivers are on the injury report. Mike Wallace (back) and Jeremy Maclin (shoulder) were limited Wednesday and Breshad Perriman (concussion) didn't practice. Maclin, who wore a red jersey signifying no contact during practice, didn't play Sunday and is taking the injury day by day. "Hopefully, this Sunday is a different situation," Maclin said.
