We want to send along our best well wishes to arguably the greatest football player in Notre Dame history: quarterback Johnny Lujack.
The 89-year-old was airlifted to the Mayo Clinic in Minnesota Monday night for a neurological examination, according to the Quad-City Times.
Despite his age, Lujack has remained incredibly active over the years. He's even continued to play at the Irish Legends golf event each year.
Lujack led Notre Dame to a national championship in 1943, 1946 and 1947. He spent the 1944 and 1945 seasons in the Navy, taking part in World War II.
Lujack won the Heisman Trophy during his senior season in 1947 and is the oldest living Heisman Trophy winner.
The Quad-City Times says Lujack has been bothered by ambulatory issues the last couple of weeks.
