Devon Still, a 2011 Big Ten Defensive Player of the Year with the Nittany Lions, announced his retirement from the NFL this week, putting an end to a pro career that was most notable for the sacrifice he made for his cancer-stricken daughter, Leah.

A second-round pick by the Cincinnati Bengals in 2012, Still's NFL career won't stand out much and that's perfectly OK; his work as a father will forever outshine anything he achieved on the field.

Still took leave from the Bengals in 2014 to care for Leah, who was facing Neuroblastoma stage four cancer. The family's story -- and Leah's unwavering spirit in the face of a heartbreaking diagnosis -- became a national sensation, resulting in TV appearances, inspirational speeches, and the best result of all: Leah being declared cancer-free in January 2016.

Still played for the Bengals, Houston Texans (joining former Penn State coach Bill O'Brien) and the New York Jets. He shared his reasoning for retirement with TMZ Sports:

"I never wanted to be somebody who gives up on their dreams, but I don't want to be somebody who chases their dream too long and misses other opportunities."

Still was also responsible for a memorable Penn State moment last year. After Penn State beat Wisconsin for the 2016 Big Ten Championship, Pro Bowl defensive end J.J. Watt had to wear blue and white, courtesy of a bet he placed with Still.

We're sure Still has many big things ahead, including his work with the Still Strong Foundation to provide support to families with children battling cancer.
