In what was originally thought to be a simple arthroscopic knee surgery, it turns out that during the offseason, Marques Colston underwent a more complicated knee procedure known as microfracture surgery. The news of the surgery comes as no surprise, given Colston missed six games in 2008 due to injuries (though mainly due to a torn ligament in his thumb). But the increased severity of a microfracture surgery -- as opposed to a simple scope -- calls into question whether Colston's fantasy value should take a dip in 2009.
