Green Bay Packers cornerback Jaire Alexander is likely to miss another game due to a shoulder injury sustained in last week's win over the Los Angeles Rams. Alexander did not practice all week and is listed as doubtful for Sunday's game against the Pittsburgh Steelers. It is not the same shoulder that he injured last season. Linebacker Quay Walker is also listed as doubtful after missing the entire week of practice. The Packers have five players listed as questionable, including three potential starting offensive linemen and two other defensive starters.
