Bears add center to practice squad

The Bears re-signed center Donovan Raiola to the practice squad Tuesday and terminated the practice squad contract of defensive end Ervin Baldwin.

Raiola was originally signed to the practice squad on Sept. 6. His contract was terminated Oct. 13, but he was gone for just a week.

Baldwin, a seventh-round draft pick in 2008 who split his time between the practice squad and active roster last season, is also expected to be back.
