Wisconsin’s depth in the secondary got a little slimmer this week.

On Wednesday morning, Jeff Potrykus of the Milwaukee Journal-Sentinel reported that safety Patrick Johnson has decided to leave the program for personal reasons. He had not been disciplined by the team.

Johnson missed Wisconsin’s season opener with a head injury.

In two seasons with the Badgers, Johnson played in 17 career games and recorded three tackles. Last year, the safety appeared in four games before suffering a season-ending arm injury.

There was no reason given behind Johnson’s decision to leave, though the defensive back has battled injuries since arriving in Madison in 2016. He was expected to have an important role in the secondary this fall.

Wisconsin opened the season with a 34-3 win over Western Kentucky in Week 1. The Badgers host New Mexico on Saturday at Camp Randall Stadium.
