Arrowhead Pride reports that center Rudy Niswanger made a return to practice today:

Kansas City Chiefs center Rudy Niswanger was a surprise return to practice this afternoon. Niswanger was carted off the field last week against the San Diego Chargers. Per Josh Looney, there are reports out there that it was a MCL sprain, which is the same injury that caused Matt Cassel to miss week one.
