Backup quarterback Matt Cassel will start the Vikings’ game against the Steelers on Sunday at Wembley Stadium in place of Christian Ponder, whom coach Leslie Frazier revealed Friday has a fractured rib.
Ponder, who ranks 30th in the NFL in passer rating (65.9), suffered the injury in the second quarter of last weekend’s loss to Cleveland and struggled with accuracy late. He underwent a CT scan Monday that revealed the fracture, but tried to practice the past two days.
“He’s a tough, tough guy, but it probably wouldn’t be wise to put him in that situation,” Frazier told reporters. “We have complete confidence that Matt will do a good job, our players are going to support him and he’ll be the guy that will be leading us to victory on Sunday evening.
