The four-year-old daughter of Cincinnati Bengals tackle Devon Still is scheduled for cancer surgery on Thursday to remove a tumor. Still posted an Instagram video in the morning showing himself giving her a pep talk as he takes her in for the operation.

Still's daughter, Leah, has been battling stage-4 pediatric cancer for three and a half months. Doctors have told Still that she has about a 50 percent chance of survival.

The Bengals signed Still, a 2012 second-round pick, to their practice squad in early September so that Leah could continue to receive health insurance. They then promoted Still to the active roster before the team's Week 2 game against the Atlanta Falcons.

Cincinnati is also selling Devon Still No. 75 jerseys and donating all proceeds to fight pediatric cancer.

Doctors successfully removed Leah's tumor after nearly five hours of surgery, Still wrote on Instagram.
