The Bears don't initially think Forte tore his ACL during Sunday's loss to the Vikings, and seem to be leaning toward an MCL issue, FOX's Jay Glazer reports.

The team will know more once further testing is done. However, even if it's as modest as a sprained MCL for the veteran, that could take several weeks to heal. Forte owners only get nine games left, and if this drags into late November the Bears would likely be well out of the playoff hunt by then.
