The move was first announced by Still's agent, Drew Rosenhaus, on Tuesday.
Still, whose four-year-old daughter Leah has pediatric cancer, has been on the team's practice squad since the end of the preseason. Still admitted he couldn't fully focus on football due to his daughter's condition, but the Bengals signed him to the practice squad so that Still continued to receive health insurance and could travel to see his daughter in Philadelphia on weekends.
On Monday, the team announced that it was donating all proceeds of Still's No. 75 jersey, priced at $100, to Cincinnati Children's Hospital and pediatric cancer research. A Bengals representative told ESPN.com that more Still jerseys were sold in a 24-hour period than any other jersey in that time span in team history.
I really wish my daughter could understand the amount of support you guys are showing her and how her fight is going to raise awareness — Devon Still (@Dev_Still71) September 10, 2014
But when she's gets older and looks back after she beats this cancer she will definitely be able to appreciate it as much as my fam — Devon Still (@Dev_Still71) September 10, 2014
At the time of Still's practice squad assignment, Bengals coach Marvin Lewis said that Still will "almost undoubtedly" be on the team's 53-man roster at some point.
Still, 25, has played in 17 games with Cincinnati, recording 21 tackles and 0.5 sacks.
