Will Green Bay quarterback Aaron Rodgers play Sunday?

Let's look at the clues and see what we can deduce.

Rodgers, appearing recovered from his broken left collarbone, practiced Thursday and looked OK. So maybe he'll play.

But though he did a little stretching and looked sharp in position drills, he watched as backup Matt Flynn, who took the majority of the reps on the day, led the offense during another short practice period. Uh, oh.

However, coach Mike McCarthy said he thought Rodgers looked "ready to play" and said he would name his starter on Friday, which might mean Rodgers has a shot.

But McCarthy also said it depends on Friday's team medical meeting, while Rodgers called it "an organizational decision."

Our deduction? It's a good thing Flynn said he's preparing this week as if he'll start against the Pittsburgh Steelers - because he probably will.

In the NFL's other major guessing game, the Vikings say running back Adrian Peterson, who sat out Sunday's win over the Eagles, remains on track to return to action for Minnesota this weekend despite being held out of practice on Thursday for treatment on his sprained right foot.

Minnesota coach Leslie Frazier said Peterson, who practiced on a limited basis Wednesday, "should be fine" to play against the Bengals at Cincinnati.

Frazier said Peterson's sitting on Thursday was just a precaution, not a setback.

Everybody hurts. New York Giants WR Victor Cruz will miss the rest of the season after having surgery on his left knee. . . . Arizona Cardinals WR Larry Fitzgerald said he practiced fully on Thursday but has one more concussion test to pass with an independent neurologist before he is cleared to play Sunday at Seattle.

Super snow day. Are you ready for Super Bowl Tuesday?

It could happen, according to the New York Daily News, if by some wild chance there's serious snowfall in northern New Jersey on Feb. 2. That's the day the Super Bowl will be held at MetLife Stadium in East Rutherford (and since it coincides with Groundhog Day, we can't consult Punxsutawney Phil to see if a blizzard is imminent - he probably has tickets to the game like the other celebrities).

But if, by some totally unlikely fluke, snow falls and it affects the game, the always-prepared NFL has a plan: Roger Goodell will stand at midfield and yell, "Snow, snow, go away - come again some other day."

Just joking - it's the game that will be held some other day.

Among the contingencies: Play it on Saturday, on Monday or Tuesday (we don't need a weatherman to predict a massive flu outbreak emptying workplaces those days), or move it to Feb. 9.

"There are postponement scenarios or rescheduling scenarios for 256 regular-season games each year. Same thing for Super Bowls since the beginning of Super Bowls," NFL senior VP of events Frank Supovitz told the Daily News. "We've had those in place. The fact is we've been in cold-weather cities before, we've been in situations where snow has fallen ahead of the Super Bowl." Of course, Super Bowl XLVIII is the first ever where snow could pile up on the field - and on the fans. Which could be fun, until it's not (say, a 52-10 blowout, with the stands emptied by the fourth quarter).
