It's not quite up to Ice Bowl standards, but if the forecast holds up the 49ers-Packers playoff game in Green Bay is going down as one of the coldest ever.

Patrick Powell, the chief meteorologist for WLUK in Green Bay, Wis., said Sunday's kickoff temperature at 3:40 p.m. (CT) is forecast for 2 degrees, with a wind-chill factor of minus-20 at Lambeau Field.

"Honestly, it's not that unusual for us," Powell said Thursday by phone. "Today, our high was 10."

In fact, Powell said, the two teams are catching a bit of a break with weather that, um, warm. The forecast for Sunday night calls for minus-20, with a wind-chill of minus-45.

Now, that would rival the Ice Bowl, the coldest NFL game ever played. That occurred Dec. 31, 1967, when the Packers beat the Dallas Cowboys with a third-and-goal sneak by quarterback Bart Starr in a game immortalized by NFL Films.

As it stands, Sunday's 49ers-Packers NFC wildcard playoff game would tie for the 10th-coldest game in NFL history -- four of the current top 10 were played in Green Bay -- based on kickoff temperature, Powell said.

The Packers practiced outside this week in preparation for Sunday. Yet, Powell doesn't think the weather gives the Packers a marked edge.

"Probably the best advantage will be early in the game because they've been practicing in it this week and they played in Chicago when it was cold last week," Powell said.

  • Niners free safety Eric Reid is looking forward to making his playoff debut at Lambeau, where his former high school teammate Eddie Lacy will be doing the same for Green Bay.

    "If anything, it's cool, because we had conversations when we were in high school about going to the NFL," Reid said. "It's both our dream, so it's awesome."

    The Duchtown High (Geismar, La.) products began their NFL careers together in the Sept. 8 season opener at Candlestick Park, a 34-28 49ers' win. They also faced off in college, with Reid at LSU and Lacy at Alabama.

    Both rookies have had exceptional rookie seasons. Reid has started every game for a defense that ranks fifth in yards allowed per game. Lacy has rushed for 1,178 yards and 11 touchdowns.

    "He's added another dimension to the team," Reid said of Lacy. "He's a workhorse for Aaron (Rodgers) when they feel Aaron needs a play off, or if they need another aspect to the game and give him the ball to run."

  • While Carlos Rogers missed his second straight practice, fellow cornerback Eric Wright came out limited from Thursday's session because of his own hamstring issue.

    Rogers was in sweats and stretching with strength coach Mark Uyeyama on a side field while practice began.

    "I'm going to have to really test it and see where I go with it, because it's not like I'm going to play in Jacksonville or Miami; I'm going to a (place) where it's 0 degrees," Rogers told KNBR 680-AM. "Playing Green Bay, they're going to throw the ball 40 or 50 times, so I'm going to be running a lot and they're going to be testing this hamstring out."

    Rogers confirmed defensive coordinator Vic Fangio's statement earlier Thursday that the injury is not as bad as initially feared, Rogers noting it's a lower-hamstring strain.

    If Rogers and Wright can't play Sunday, the 49ers cornerback corps would likely feature Tramaine Brock and Tarell Brown as starters with only Perrish Cox and Darryl Morris in reserve. The Packers use at least three wideouts 75 percent of the time, Fangio said..

  • Short-yardage situations is an area "we need to improve," offensive coordinator Greg Roman said. The 49ers failed to convert on four short-yardage plays in last week's win at Arizona, including loses of minus-5 yards on each of their third-and-1 rushing attempts.

    They're 9 of 17 on third-and-1 runs this season for a 52.9-percent success rate that ranks fourth-lowest in the league. That's better on second-and-1 runs (12-of-17). On third-and-2, they've converted 1-of-6 runs, but 6-of-9 passes.

  • Ed Hochuli will serve as referee in his first playoff assignment since the 49ers' NFC Championship game loss in January 2012. Hochuli nullified a potential New York Giants fumble with two minutes left when he ruled Ahmad Bradshaw's forward progress had been stopped. Hochuli has since worked two 49ers games: December 2012 at New England and this past Oct. 27 against Jacksonville in London.

  • Linebacker NaVorro Bowman's case for NFL Defensive Player of the Year picked up steam Thursday when the NFC named him its Defensive Player of the Month for December.

  • Defensive tackle Justin Smith, center Jonathan Goodwin and wide receiver Jon Baldwin returned to practice after missing Wednesday's session.
