The Cam Newton watch continues.
After missing Wednesday's practice with rib soreness, the Carolina Panthers quarterback was limited during Thursday's session and didn't throw a pass during the portion of practice open to the media.
The fourth-year passer has never missed an NFL start but acknowledged that he won't put his team at risk by playing before he's ready. We might not have our answer until shortly before Sunday's 4:25 ET kickoff.
It's a positive sign that Newton took the field Thursday, but after what we saw from Gerald McCoy and the Bucs' defensive line this August, a less-than-healthy Newton is a pressing concern for last year's NFC South upstarts.
UPDATE: NFL Media's Jeff Darlington reported that Newton was throwing passes at Friday's practice.
