#Packers practice: Morgan Burnett joins Casey Hayward as only two active players on sideline during practice. McCarthy at 12:30 CT

Considering Morgan Burnett took part in practice on Monday, Wednesday and Thursday, it came as unexpected he missed the Packers' final tune-up session on Friday before their season-opening game against the San Francisco 49ers.
Burnett injured his hamstring in the team's third preseason games against the Seattle Seahawks and was withheld from the preseason finale against Kansas City Chiefs last week.
It appeared Burnett had been recovering nicely based upon his return to practice earlier in the week.
Whether he suffered a setback or the Packers are just playing things safe and taking it easy with Burnett is currently unknown.
Game day status reports will be released later this afternoon, and head coach Mike McCarthy will address the media at 12:30 p.m. CT, according to the team's official website.
If the Packers were forced to miss Sunday's game without Burnett, it would be a blow to a defense that's looking for an answer to quarterback Colin Kaepernick and the rest of the 49ers offense.
M.D. Jennings and Jerron McMillian would figure to replace Burnett in the starting lineup should Burnett miss any time, just as they did in the preseason finale.
UPDATE at 12:50 p.m.: Burnett was officially announced as questionable for Sunday's game, ostensibly giving him a 50/50 chance of playing against the Niners.
