Packers' Cobb optimistic he'll play vs. Bears

Green Bay Packers wide receiver Randall Cobb said he's optimistic about playing Thursday against the Chicago Bears after being a full participant in practice Tuesday, according to NFL Network's Omar Ruiz.

He missed Week 3 with a chest injury.

With Cobb sidelined, Geronimo Allison exploded for 122 yards on six catches in Green Bay's overtime win.

Cobb was his usual efficient self over the first two games of the year, racking up 15 catches for 145 yards.
