According to the team's official website, Coleman and Vince Young are expected to get a fair share of the workload against the Arizona Cardinals this evening, while starter Aaron Rodgers and backup Graham Harrell will also contribute.
The head coach told reporters: "Frankly, it's the responsibility of the coaching staff, particularly myself calling the game, to get [Coleman] comfortable to where he can just go play. That's what we'll be working on here the next 30-plus hours."
Young, who joined the Packers earlier this week, added: "I just want to make sure I've got the right plays, make sure I get the guys out of the huddle. I don't want any delay of games or things like that. That's the biggest thing about being a quarterback, getting guys into the right position and running the right routes."
It will be the first time that the Packers have used four quarterback in one game since they played the Pittsburgh Steelers during the 2007 pre-season.
