This kind of came out of nowhere. Matt Forte had knee surgery. Here is the link from the Chicago Tribune.
The clean-up procedure followed a post-season MRI. Forte sprained the medial collateral ligament in his knee during the Bears' 25-19 victory at Seattle in Week 3, but it is unclear if the surgery stems from that specific injury.
As always, as soon as we get any more info, we'll be sure to pass it along.
Also in the same article the Trib is reporting that Brad Maynard had his hip scoped.
