New England quarterback Matt Cassel practiced with the team on Friday, but his status for Sunday's game in Oakland is still uncertain after the recent death of his father. "We'll do our thing after practice and let you know," Coach Bill Belichick said before the team's practice. Cassel left the team on Wednesday after his father died Monday night. Cassel was notified of his father's passing on Tuesday but stayed with the team before flying to Southern California to be with his family. "He seems to be doing really good," teammate Ty Warren said of Cassel. "Guys in the locker room have been supporting him. He's our family. What he's dealing with is a difficult thing, but we're here for him."
