Arnold confirmed that Broyles isn't in hospice care, but "on" hospice, after several Twitter posts suggested otherwise, according to Kersey.
"That little word makes a big difference," Arnold said. "When you go into hospice, you're talking very little life expectancy left. You're in a facility. That is end of life.
"But you can sign up for hospice and they can come to your house for six months. Sometimes people will graduate off of hospice. This is more quality of life management."
Arnold also confirmed that Broyles was in good spirits despite the setback.
"He's really happy," she said. "Really enjoying talking about football and all those things. He's really happy and enjoying life."
Broyles achieved a high level of success on the sidelines, leading the Razorbacks to a 144-58-5 record from 1958-76, and winning seven conference championships and a national title in 1964.
He was named athletic director at Arkansas in 1974, a position he held until 2007. The annual award for the top assistant coach in the nation also bears his namesake, with a list of winners including current head coaches Lincoln Riley (Oklahoma), Tom Herman (Texas), Pat Narduzzi (Pittsburgh), Gus Malzahn (Auburn), and Kirby Smart (Georgia).
