McCaffrey (hamstring) wasn't present at the part of Thursday's practice open to the media, Darin Gantt of the Panthers' official site reports.
On the heels of four consecutive limited practices, McCaffrey appeared to be progressing in the right direction as of Wednesday's session. Afterward, coach Matt Rhule called McCaffrey's odds to return this Sunday from a strained hamstring "50-50," per David Newton of ESPN.com. There's still a chance McCaffrey gets on the practice field after the media are ushered out, but his activity level on Thursday's injury report now bears watching to see if those odds may have dipped.
