Cook suffered a tear of the meniscus in his left knee in Week 3 against Detroit. That marked his regular-season debut after he tore the meniscus in his right knee in an exhibition game.
Cook, who was limited in practice Wednesday and Thursday, could take over the starting role at the right corner when he does come back.
Cedric Griffin was the starting right corner after returning from a torn ACL in his left knee in Week 3, but he tore the same ligament in his right knee Oct. 11 against the Jets and has been placed on injured reserve.
"I want to (play)," said Cook, who is working at both corner spots. "I'm taking reps with the defense, and the plan is to play on Sunday."
Last Sunday against Dallas, the Vikings used Antoine Winfield as their starting left corner and Asher Allen on the right side. Winfield slid inside and Lito Sheppard played the left corner in the nickel.
However, the Cowboys got three touchdowns against Sheppard, and ideally the Vikings would use a rotation that includes Winfield and Cook as the starters and Allen in the nickel.
If Cook does play Sunday, the Vikings will have to monitor his reps because of the time he has missed. That could mean that Winfield and Allen would start and Cook would be used only in nickel situations.
SERIES HISTORY: 98th regular-season meeting. Packers lead series, 49-47-1. The Vikings have won the past three games in this rivalry, and if they win on Sunday it will be the first time since 1992-93 that Minnesota has won four consecutive games against the Packers. The Vikings also won the only playoff meeting between these teams, beating the Packers 31-17 in a wild-card game during the 2004 season.
QUOTE TO NOTE: "I think the biggest thing is you have to go out and start the first quarter fast. It's hard to get in a hole on the road. The other thing is we need to create turnovers. Offense needs to take care of the ball. Those are the two biggest things. Get off to the hot start and takeaways." — Linebacker Chad Greenway on what it will take for the Vikings to end their six-game road losing streak that dates to last season. The last time the Vikings won on the road was Nov. 1, 2009, at Green Bay.
Jon Cooper appears to have settled in as the Vikings' starting center for as long as John Sullivan is sidelined by a calf injury.
Cooper replaced Ryan Cook in the second half on Oct. 11 against the New York Jets and got his first career start last Sunday in a victory over the Cowboys.
An undrafted free agent out of Oklahoma in 2009, Cooper spent the first four weeks of last season on the practice squad before being promoted to the 53-man roster.
He had a few issues with shotgun snaps against the Cowboys but got a passing grade for his work against Dallas Pro Bowl nose tackle Jay Ratliff.
