Minnesota Vikings coach Leslie Frazier says he wants to see how Christian Ponder's injured ribs progress through the bye week before he makes a decision on a starting quarterback.
Frazier spoke Tuesday, two days after backup Matt Cassel helped engineer the Vikings' first win of the season. Cassel completed 16 of 25 passes for 248 yards with two touchdowns and no interceptions in a 34-27 victory over the Steelers in London on Sunday.
Ponder has struggled mightily early this season. He completed just 59 percent of his passes with two touchdowns and five interceptions in the first three games, all losses for the Vikings.
Frazier says it's hard to make a decision until they know if Ponder will be healthy enough to play against Carolina on Oct. 13.
