Lou Holtz, one of the most famous college football coaches of all-time, has reportedly tested positive for COVID-19.

That’s according to Mike Gillespie of ABC Columbia:

The report also says that he’s recovering from the virus but that he doesn’t have a lot of energy because of it.

Holtz, 83, coached in college football for 33 years and is most famous for being the head coach of the Notre Dame Fighting Irish. At Notre Dame, he amassed a 100-30-2 record and a National Championship during the 1988 season.

Holtz also coached at William & Mary, North Carolina State, Arkansas, Minnesota, and South Carolina. He’s the only coach to lead six different programs to bowl games throughout his coaching tenure. Before that, he was a linebacker at Kent State.

In addition to being a coach, Holtz was a longtime college football analyst for ESPN until 2015.

Here’s to a speedy recovery for the legendary coach.
