Legendary college football coach Lou Holtz has tested positive for COVID-19 and is recovering, though he admitted that he doesn’t have a lot of energy.

The report came from Mike Gillespie of ABC-Columbia, the same city where Holtz led the Gamecocks from 1999-2004, and a 33-37 record. Holtz had a 33-year career and finished with an overall record of 249-132-7.

He was enshrined into the College Football Hall of Fame in 2009. He may be most known for his work at Notre Dame, where he coached the 1988 Irish national championship team and won 100 games in 11 seasons as Irish head coach.

Holtz, 83, is the only coach in the history of college football to take five different teams to a bowl game (his ’85 Minnesota team actually qualified as a sixth, except Holtz did not coach in the bowl game since he had accepted the Notre Dame job), win four bowl games with different teams — and have four different college teams ranked in the final top 20 poll, according to Notre Dame.

Since he left coaching, Holtz made a name for himself as a college football studio analyst on ESPN and an on-site analyst for college football games.
