All proceeds from sales of the jerseys, priced at $100, are being donated to Cincinnati Children's Hospital and pediatric cancer research.
In June, the defensive tackle announced that his four-year-old daughter, Leah, had been diagnosed with pediatric cancer and would undergo chemotherapy.
Still admitted earlier this month that he couldn't focus on football due to his daughter's condition, and while the Bengals waived him, the team placed him on its practice squad so that the defensive tackle could continue to receive health insurance and travel to see Leah on weekends.
"They could have just washed their hands completely of it," Still said. "Say we don't care what's going on in his personal life, we just want people who can care 100 percent on football, that's what they pay us to do. But they thought about my personal issues and allowed me to come back on the practice squad so I still have insurance."
Bengals coach Marvin Lewis said at the time 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.
