Matt Cassel was suited up and participating in today's practice, the first of the week for the Chiefs as they get ready for Sunday's game against the Rams in St. Louis.
During the brief portion of practice open to the media, Cassel was running with his teammates (though he lagged behind the other quarterbacks). He stretched and then was first in line, a position reserved for the starter, when the quarterbacks started throwing.
He was handing off to running backs while Brodie Croyle and Tyler Palko started position drills by throwing to the wide receivers. Cassel later was in the huddle and did some throwing during a drill in which all three quarterbacks, each with a ball in hand, throws to a receiver down the field.
Cassel threw three deep passes but only one with a strong zip. He showed good accuracy, there was no defense in place.
My guess on his availablilty Sunday? There's clearly a chance he will play against the Rams. Otherwise, the Chiefs wouldn't have allowed him to be practicing. But it also appears the Chiefs aren't counting on him being ready.
