At last night's ESPYs, an emotional Devon Still took the stage to accept the Jimmy V Perseverance Award on behalf of his 5-year-old daughter, Leah.
Leah Still's battle with pediatric cancer was well documented this past year, with #LeahStrong becoming a Twitter rallying cry -- not only for Leah but for everyone struggling with cancer worldwide.
Leah is currently in remission, but due to her ongoing treatment, she was unable to attend last night's event.
Courageously, her father took the stage for her.
Fighting back the tears, he said,
I know you wish you could be here, but I know you're watching. And I just want to thank you. From the moment you was born, you molded me into the man I am today.
