However, he didn't sound optimistic his next scan this week will reveal significant changes to the status of his injured collarbone.
"I think you can probably guess," Rodgers said on his weekly ESPN radio show.
"I have an idea what it's going to look like based on the previous one, the amount of days we have between scans, project that forward to a similar amount of days and have a pretty good idea and provide over-radiation."
Rodgers has been sidelined since suffering a fractured collarbone on his non-throwing left side early in the November 4 loss to the Chicago Bears.
Steelers coach Mike Tomlin said that Pittsburgh will worry about Rodgers when the Green Bay Packers decide the quarterback's status for Sunday game.
"We are not going to worry about (Rodgers) until we find out for sure," Tomlin said, adding that practices will focus on scheme, not one quarterback or the other.
Cincinnati Bengals punter Kevin Huber will have surgery to repair his broken jaw, the team announced.
Huber, who was placed on injured reserve, sustained a broken jaw and cracked vertebrae when popped by Pittsburgh Steelers linebacker Terence Garvin during a first-quarter punt return in Sunday night's 30-20 loss to the Pittsburgh Steelers.
The Jacksonville Jaguars have placed wide receiver Cecil Shorts and guard Will Rackley on injured reserve.
Shorts, who leads the Jaguars with 66 catches for 777 yards, battled a groin injury for much of the season. Rackley missed two games earlier this year with a concussion.
The Denver Broncos have signed free agent defensive end Jeremy Mincey, who was released by the Jacksonville Jaguars last week for being late to a team meeting.
Mincey is expected to be on the practice field Wednesday.
Pittsburgh Steelers outside linebacker LaMarr Woodley has been ruled out to play Sunday against the Green Bay Packers because of an injured right calf.
Woodley also could also miss the regular-season final against the Cleveland Browns.
Dallas Cowboys middle linebacker Sean Lee could miss the rest of the 2013 season with a sprained ligament in his neck.
Lee was injured at Chicago in the Cowboys' loss on Dec. 9 and practiced two days in preparation for Week 15 against the Green Bay Packers. But Friday he was ruled out with nagging discomfort.
Lee is expected to be evaluated further this week but surgery was not considered necessary.
Running back Shaun Draughn has signed with the Indianapolis Colts, who placed inside linebacker Pat Angerer on injured reserve.
Angerer played in 11 games (nine starts) this season and totaled 87 tackles (48 solo), a half of a sack, two passes defensed and an interception.
Draughn appeared in 20 career games since entering the NFL as an undrafted free agent with the Washington Redskins in 2011.
Baltimore Ravens quarterback Joe Flacco has said his knee is fine and he expects to be ready to go Sunday.
Flacco took a hit on his left knee from linebacker DeAndre Levy of the Detroit Lions, but Levy was not penalized.
"It was more probably scary than anything, just from what I felt," Flacco said. "And also trying to get a couple yards out of (the hit). It feels fine. It feels strong."
