CHARLOTTE, N.C. -- The 49ers' road to Super Bowl XLVIII will remain, well, on the road.
If the 49ers win Sunday's divisional-round game against the host Carolina Panthers, next up will be the NFC Championship game in Seattle, where the Seahawks defeated the New Orleans Saints 23-15 on Saturday.
Only three wild-card teams have won strictly road playoff games en route to a Super Bowl win: the 2005 Pittsburgh Steelers, 2007 New York Giants and 2010 Green Bay Packers.
Before this season, the 49ers had never played back-to-back road playoff games, much less three straight. But Sunday's game at Carolina marks the second straight playoff game away from Candlestick Park for the 49ers, who advanced with a 23-20 wild-card win last Sunday at Green Bay.
The 49ers won last season's NFC Championship in 28-24 fashion at Atlanta before falling in Super Bowl XLVII to the Baltimore Ravens 34-31 in New Orleans.
Had the sixth-seeded Saints upset the top-seeded Seahawks on Saturday, the No. 5-seed 49ers could have set up the first conference championship game between Nos. 5 and 6 seeds. Since that scenario didn't unfold, Candlestick indeed has hosted its final 49ers game, a 34-24 win over the Atlanta Falcons on Dec. 23.
The 49ers are trying to become the third team to win a Super Bowl after losing in it the previous season, a feat pulled off only by the 1971 Cowboys and '72 Dolphins.
Vikings general manager Rick Spielman already has interviewed at least five coordinators: Mike Zimmer (Bengals, defense), Todd Bowles (Cardinals, defense), Darrell Bevell (Seahawks, offense), Dan Quinn (Seahawks, defense) and Ray Horton (Browns, defense).
Roman, 41, on Wednesday did not confirm nor deny an ESPN report that he interviewed Monday in Chicago for the since-filled Penn State post. He's been an offensive coordinator under Jim Harbaugh since 2009 at Stanford.
Tomsula, 45, joined the 49ers in 2007 as their defensive line coach. He won the 2010 regular-season finale as the interim coach after Mike Singletary's firing. Tomsula was the Rhein Fire's coach in 2006 in the now-defunct NFL Europe.
Roman's pending interview with the Vikings was first reported by ESPN, and Tomsula's by Fox Sports.
Sunday's forecast calls for sunny skies and temperatures in the mid-50s, according to the National Weather Service. Bank of America Stadium's field was covered by a tarp during Saturday's rainstorm.
