FFToday's Take:The link provides footage of how the injury happened; suffice it to say Mathews faces long odds of playing this week with any kind of effectiveness if he is somehow cleared in time. Making matters worse, Mathews' long injury history and the opponent this week (the Denver Broncos) are also working against him. Donald Brown has overtaken Branden Oliver in recent weeks, but the two would likely share touches if Mathews is forced to sit out.
