Are injuries starting to take their toll on the Packers' offensive line? That certainly is the case at left tackle, where veteran Chad Clifton's status remains very iffy as a result of the hamstring injury he suffered a few weeks back. Head coach Mike McCarthy offered no clues on the future availability of Clifton when he said a decision will be made on the tackle's status at some point during the team's upcoming bye week. Meanwhile, team sources' eyebrows were raised more than a little when starting ORG Josh Sitton suddenly popped up on the midweek injury report before the team's Week Seven game in Minnesota with a knee ailment that forced him to sit out practice. While Sitton has established himself as one of the league's top guards, daily team observers believe his play has tailed off a bit, and it's quite possible a tender knee could have something to do with the drop-off.
