Leah Still is the daughter of Cincinnati Bengals defensive lineman Devon Still, and she's been an inspiration to many in the way she's fought to overcome cancer since being diagnosed with the disease in 2014.
Still delivered an emotional speech at the 2015 ESPY Awards, when he accepted the Jimmy V. Perseverance award on his daughter's behalf a couple of weeks back.
Now, as he prepares to leave for training camp with the Bengals, he shared a portion of his heartfelt goodbye to his daughter on his Instagram page. Just make sure you have a tissue handy before you watch.
