This is going to be a short one.
Per Jay Adams at the official site, Sean Weatherspoon and Ovie Mughelli couldn't practice. No idea what's going on with Mughelli, but I will try to find out. It doesn't look like 'Spoon's going to get a full week of practice in, so you can almost certainly rule him out with Stephen Nicholas still playing like a decent linebacker.
Dunta Robinson, John Abraham and Curtis Lofton were all limited. The only one I'm concerned about is Dunta, who is still recovering from his concussion. I'd expect Abe and Lofton to be back to killing people full-time.
Check back tomorrow and we'll see if these dudes are making progress.
