Devon Still gives his daughter amazing pep talk before her cancer surgery

Are you ready for the best pep talk by an NFL player this season?

No, it had nothing to do with a game.

Also,  the man who performed it is on bye this week.

But Devon Still, the Cincinnati Bengals tackle whose amazing story has been told often, knew he needed to be strong for his 4-year-old daughter, Leah, as she prepared to have surgery at the Children's Hospital of Philadelphia. Still captured the moment on video and posted it to his Instagram account on Thursday. (h/t ESPN):

Sounding confident, Still asks a brave Leah a very important question.

"I'm going to ask you again," he said. "Are you ready for today? I'm ready for today."

She smiles. There isn't an ounce of fear in her eyes. She nods and says, "Uh huh."

Still reaffirms the goal for her surgery, scheduled for Thursday.

"You ready to get this cancer up out you?" he asks.

Once again, a smile and a nod.

Still: "Let's do it. Fist bump."

Naturally, she returns the favor.

With the Bengals off for Week 4, Still will be by Leah's side the entire time — just as he has been since the day in June when doctors discovered that she suffered from neuroblastoma, a very serious form of pediatric cancer. Her tumor has subsided since the last time they measured it, and they are hoping to remove it before she faces another round of chemotherapy, radiation and stem-cell transplants.

What an incredibly brave little girl. And what a supportive father.

No wonder that Still's Bengals jerseys have been flying off shelves, with 100 percent of the proceeds going to support pediatric cancer. Even New Orleans Saints head coach Sean Payton chipped in on the jersey sales, buying 100 of them — nearly $10,000 worth — to donate to Cincinnati-area children.

Still had been cut by the Bengals after training camp, and he said it was the right move — that his focus had not been 100 percent on football with all of Leah's medical concerns consuming him. But the team re-signed him to its practice squad as a way of financially supporting him, and the Bengals later added him to the active roster once more.

The Bengals allowed Still to leave a day early to throw Leah a pre-surgery party at a movie theater he rented out. And you can bet she has as good a support system to help her get through this scary time.

Then again, does she look scared? Amazing.
