Frank Gifford‘s legacy is living on through his children, who have posted emotional tributes to the late sportscaster.

Cody Gifford, Frank’s 25-year-old son with the Today show’s Kathie Lee Gifford, shared a photo of the former New York Giant “meeting his great grandchild.”

“Thank you, everyone,” Cody wrote in the caption, adding the hashtags “#fighton #liveon.”

Frank died of natural causes Sunday in his Connecticut home.

“We rejoice in the extraordinary life he was privileged to live, and we feel grateful and blessed to have been loved by such an amazing human being,” his family said in a statement. “We ask that our privacy be respected at this difficult time and we thank you for your prayers.”

Cody’s sister Cassidy, 22, also honored her father on social media Monday.

“Very few people are blessed enough to call their father a legend, and an even smaller number are able to share that notion with the rest of the world,” she captioned an Instagram of herself as a child, carried on her dad’s shoulders.

“Yesterday, I lost my best friend,” she continued. “His kindness was infectious, and his grace, beyond compare .. And despite the worldly passing of an incredible man, I undoubtedly know heaven gained one stud of an angel.”
