Halftime: Randall Cobb returns after injury

GREEN BAY, Wis. -- I have one quick halftime note here as the Green Bay Packers hold a comfortable 21-7 lead over the Arizona Cardinals.

Three significant Packers players departed with injuries in the first half, and only one came back. That was receiver/returner Randall Cobb, who injured his left shoulder on a punt return in the second quarter and missed the next offensive series. But Cobb was back on the field just before halftime to field a punt.

Receiver Jordy Nelson (ankle) and right tackle Bryan Bulaga (hip) did not return after suffering their injuries. The guess here is they won't be back.
