* Vikings backup quarterback fails to get offense in gear (Adds detail)
Jan 5 (Reuters) - The Green Bay Packers charged into the second round of the National Football League playoffs with a routine 24-10 win over a Minnesota Vikings team that was dealt a huge blow before the game even started.
Vikings starting quarterback Christian Ponder had a throwing session during warmups but was declared inactive with a bruised right elbow in a surprise announcement about 90 minutes before the NFC wild-card game began.
Green Bay's Aaron Rodgers completed 23-of-33 passes for 274 yards and one touchdown and the Packers stymied a Minnesota passing game that was forced to start quarterback Joe Webb, who had not attempted a pass in the 16-game regular season.
Without Ponder, the Vikings were a shadow of the team that edged Green Bay 37-34 in last week's regular season finale. Ponder was hurt during that game but finished with a career-high passer rating and three touchdowns.
The Packers move on to the second round on Jan. 12 when they visit the San Francisco 49ers.
Webb struggled to get the Vikings offense going despite a promising start which resulted in a field goal on Minnesota's first drive for an early 3-0 lead.
But a nine-yard touchdown run from DuJuan Harris, a 20-yard Mason Crosby field goal and two touchdowns from fullback John Kuhn, the second on a nine-yard pass from Rodgers, put the game out of reach.
Webb managed to take advantage of confusion in the Packers defense late in the fourth quarter, finding a wide open Michael Jenkins with a 50-yard touchdown pass that pulled the Vikings to within 14 points with under four minutes to play.
