By now, you probably know the story of Devon Still. The defensive tackle was cut by the Cincinnati Bengals in the preseason before being offered a spot on the team’s practice squad so that he could pay for his young daughter’s cancer treatments. Still eventually made the Bengals active roster and his jersey became the top-selling uniform in the team’s franchise history, with all of the proceeds going to cancer research.

Still’s daughter, Leah, is currently undergoing treatment for stage 4 neuroblastoma, but she appears to be in good spirits. That might be helped by the fact that her father is pretty good at giving pep talks like the one he shared via his Instagram on Thursday morning:

It’s incredibly adorable all around. I have faith that Leah’s gonna crush it today.
