The only Carolina Panthers player not to participate in practice Friday was safety Chris Harriswho is still dealing with a knee injury and is considered doubtful for Sunday's game agaist the Atlanta Falcons. This likely means another start for safety Quinton Teal in the defensive secondary. Listed as questionable for the Panthers is DT Nick Hayden. OL Jeff Otah has now upgraded to probable along with RB Jonathan Stewart and DE Everette Brown. Look for all but Harris to be available Sunday to take on the Falcons. The biggest question remaining is who will be Jake Delhomme's back up and who will be third string QB, Matt Moore or AJ Feeley?
