Arizona Cardinals wide receiver Larry Fitzgerald is probably doing what every other football does during the offseason—spending time with family and training for next season. But it appears that he is also taking the time to visit a sick friend and fan, Arizona Senator John McCain.

The senator’s wife posted a picture on Instagram of Fitzgerald's visit to the family's cabin. It included the caption: “Look who came for a visit today,” Cindy McCain wrote. “Our favorite Cardinal and a wonderful human being!”

The two have become friends over the course of Fitzgerald’s 14 seasons with the Cardinals. So, it should come as no surprise that Fitzgerald is taking the time out of his schedule to visit him.

Senator McCain was diagnosed with a brain tumor last year, glioblastoma. He spent some time in the hospital in Maryland late last year for a viral infection. He was also feeling some side effects from the chemo and radiation treatments doctors are using to fight his cancer.

But he was able to return to Arizona a week before Christmas where he has remained. Initially, he had intended to return to Washington in January. But according to Dan Nowicki of the AZCentral.com, his daughter said the family decided to keep him home due to fears over the flu.

There were concerns over whether Fitzgerald would be returning for another season next year or retiring. The team shared the good news (he’s returning) with fans on Twitter earlier this month.
