Vikings put Matt Cassel on IR

— -- The Minnesota Vikings placed Matt Cassel on season-ending injured reserve with broken bones in his left foot meaning rookie Teddy Bridgewater will remain in the starting role for the rest of the season.

The Vikings also placed guard Brandon Fusco on injured reserve. To fill their roster spots the team signed tight end Chase Ford and offensive lineman Austin Wentworth from the practice squad.

Bridgewater made his NFL debut on Sunday in relief of Cassel, completing 12 of 20 passes for 150 yards in the Vikings' 20-9 loss to the Saints.

Cassel injured his foot on a scramble during a Vikings field-goal drive early in the second quarter. He was carted to the locker room for X-rays after trainer Eric Sugarman examined his foot. 

The Vikings named Cassel their starting quarterback at the beginning of the season, and had planned not to have a "quick hook" with him, as coach Mike Zimmer put it.
