A doctor will be at Matt Cassel's side Sunday in St. Louis to provide final advice on whether or not the Kansas City Chiefs' quarterback should play 11 days after having an emergency appendectomy.
Chiefs coach Todd Haley said Friday that Cassel's availability against the Rams remains uncertain. The quarterback was limited in practice again Friday and officially listed as questionable.
"Without getting into details, (evaluation) has been ongoing because this isn't your run-of-the-mill injury that a lot of us have a lot of experience with, so we do have to lean to the doctors a bunch in making sure that the right thing's being done," Haley said, according to the Chiefs' website.
In the early part of drills that reporters are allowed to watch, Cassel appeared to throw the ball without any problems. But he didn't fully participate in the pre-workout stretching exercises.
Cassel sat out last week against the San Diego Chargers while the Chiefs, behind Croyle, had one of their worst offensive showings ever and lost 31-0.
