Dan Voltz is calling it a career.

The Wisconsin preseason All-American, who was working his way back from a torn anterior cruciate ligament, is stepping away from football.

Wisconsin coach Paul Chryst made that announcement on Tuesday in practice.

Voltz was considered by many as one of the nation’s top offensive linemen. He tore his ACL last year against Illinois and was slated to solidify the Badger offensive line.

He started in 27 of the 32 games he played in his Wisconsin career, which included a second-team All-B1G nod in 2014. Volta was scheduled to move to guard this season following Michael Deiter’s emergence in 2015.

The Badgers do still return three starters on the offensive line. Deiter, Beau Benzschawel and Jacob Maxwell will look to step up without Voltz. Micah Kapoi will likely fill Voltz’s spot at guard.

Wisconsin will look to bounce back from a rare off year in the rushing department without Voltz. The Badgers are set to face five top-15 teams in their first six games of the 2016 season.

Now, that mountain is even steeper.
