Matt Cassel will start at quarterback for the Minnesota Vikings on Sunday, replacing injured Christian Ponder against the Pittsburgh Steelers when the teams meet at Wembley Stadium in London.
Christian Ponder attempted to practice with what was revealed Friday as a fractured rib. He was on the practice field for the third straight day, but coach Leslie Frazier is giving Cassel the start for the winless Vikings.
Frazier said Ponder, who is 30th in the NFL in passer rating at 65.9, has a rib fracture. Ponder said Friday the injury is near his heart.
The embattled quarterback, booed mightily in his home stadium in Minneapolis last week, split repetitions with Cassel Wednesday and Thursday.
Cassel was released by Kansas City after the Chiefs went 2-14 last season. He has 30 turnovers in his last 18 games.
---Tampa Bay Buccaneers quarterback Josh Freeman told ESPN in an interview that aired Thursday night that a trade is "probably the best option" for him.
