While Friday wasn't Leah Still's actual birthday, her grateful dad was celebrating like it.

Houston Texans defensive lineman Devon Still marked the one-year anniversary of Leah, 5, being in remission from pediatric cancer with a heartwarming Instagram photo celebrating the important milestone.

"I want to wish a Happy (2nd) Birthday to my baby, Leah,'' Devon wrote. "Today, March 25th, marks a year of her being in remission! A day she was given a second chance at life. There's not enough hours in a day, days in a month, or months in a year to tell you how much I love you and how proud of you I am."

Leah underwent her final treatment on Jan. 12, celebrating a happy day in a fight that began in June 2014 when she was given a 50-50 chance to live by doctors after being diagnosed with Stage IV neuroblastoma. She followed by walking the New York Fashion Week runway a month later.

During her public fight, Leah helped raise more than a million dollars for cancer research, won an ESPY Award for her courage, and formed a close bond with TODAY's Hoda Kotb after appearing in the "Truly Brave" video starring Cyndi Lauper and Sara Bareilles that was produced by Kotb.

Leah celebrated the last round of her treatments in January by hanging out with Cleveland Cavaliers superstar LeBron James. That month was also important for Devon, who signed a futures contract with the Houston Texans for the 2016 season.

In September 2014, the Cincinnati Bengals kept Devon on the practice squad on purpose so that he would have health benefits to pay for Leah's treatment, and later signed him to the 53-man roster. His No. 75 jersey became a symbol of Leah's fight, with the Bengals presenting a $1.3 million check to the Cincinnati Children's Hospital from sales of the item.
