Minnesota Vikings quarterback Christian Ponder played perhaps the best game of his career in the Vikings' victory over Green Bay last week that got the Vikings into the playoffs. But he sustained an injury in that game that could keep him out of Saturday's wild-card playoff game against the Packers.
Ponder is listed as questionable for Saturday game with an elbow injury, and he has been limited in practice all week.
On Thursday, Vikings coach Leslie Frazier said he thought Ponder would be all right to start Saturday's game, but Friday's listing made that less certain.
Joe Webb would be the Vikings' quarterback if Ponder can't play or if Ponder aggravates his injury during the game.
The Vikings' offense is centered around Adrian Peterson, but Ponder played a major role in Minnesota's 37-34 victory over the Packers on Sunday, throwing three touchdown passes with no interceptions.
Webb has not attempted a pass this season.
Vikings cornerback Antoine Winfield is also listed as questionable with a broken right hand.
