[ESPN.com] Chiefs quarterback Matt Cassel had his most extensive practice in the past three days Friday and remains hopeful of playing Sunday against the St. Louis Rams.

The Chiefs listed him as questionable and said they won’t determine whether or not he will play until he is examined by the medical staff on Sunday. Cassel is recovering from an appendectomy that sidelined him last week.

He’s been listed for limited participation this week, but reporters who saw Cassel early in Friday’s practice noted he was throwing the ball with more velocity and appeared to be doing more with the offense in practice.
