The Bears, who face the San Francisco 49ers on "Monday Night Football," are preparing for a scenario in which Cutler could miss some games after being concussed Sunday during the Bears' 13-6 loss to the Houston Texans.
Cutler has had concussion issues in the past.
McCown, 33, was out of the NFL in 2010 and has played six games from 2008-12.
Let's just say the Bears offense is in trouble if they ever reach a point where McCown takes the field.
UPDATE: The Bears made it official Tuesday, announcing that McCown has in fact re-signed.
