Should Matt Cassel be allowed to play or not allowed to play this week following appendectomy that he had...?

...yesterday? Even if he declares himself healthy or whatever its called. At the same time it was a laparoscopic one. Wasn't like the one that Ben Roethlisberger had (emergency one and mostly traditional surgery one), a few yrs back. It was just before the season opener and after winning the super bowl the year prior to it as well.
