Brett Favre will start against the Bears tonight while Adrian Peterson has been deactivated.

Peterson was expected to be in the lineup for tonight's game despite missing practices earlier this week because of a knee injury suffered when he collided with teammate Tarvaris Jackson in last week's loss to the Giants. Rookie Toby Gerhart will start in his place.

Favre threw several passes approximately three hours before the game under the watchful eye of Vikings offensive coordinator Darrell Bevell, quarterbacks coach Kevin Rogers and members of the training staff.

Earlier this week, Favre found it too painful to throw during practice. Earlier Monday, the Vikings requested and were granted permission to upgrade Favre's status from "out" to "questionable."

Here are the Bears' inactives: quarterback Caleb Hanie, cornerback Joshua Moore, running back Kahlil Bell, linebacker Pisa Tinoisamoa, guard Herman Johnson, guard Edwin Williams, tight end Desmond Clark and defensive lineman Marcus Harrison.

For the Vikings, quarterback R.J. Archer, quarterback Patrick Ramsey, receiver Greg Lewis, safety Tyrell Johnson, safety Jamarca Sanford, tackle Thomas Welch and defensive tackle Jimmy Kennedy were inactive.
