Professional career
Cincinnati Bengals
At the 2012 NFL Draft, Still was selected in the second round by the Cincinnati Bengals, with the 53rd overall selection. He played two seasons with the team before being cut in late August 2014, prior to the start of the season. The following day, the Bengals re-signed Still to the practice squad to help him pay for his daughter's cancer treatment. In addition to his daughter Leah's diagnosis, Still was also attempting to heal from a hamstring injury. He admitted that he would not be able to impact to his full ability and give the best effort to his team. Consequently, Still did not make the Cincinnati Bengal's 53-man roster. Still said: "I completely understand where they were coming from...."I can't give football 100 percent right now. In the business aspect they want guys to solely focus on football, which is understandable. We are here to win this city a Super Bowl and right now I am not in a position where I can give football 100 percent of everything I have." Head coach Marvin Lewis offered Still a position on the practice squad so that he could continue to pay for his daughter's cancer treatments. As a member of the practice squad, Still did not have to travel with the team on road trips. On September 10, 2014, it was announced that Still would be moved to the active roster. In the game that followed, the Bengals' second of the season, he recorded three tackles against the Atlanta Falcons. On September 5, 2015, Still was waived by the Bengals.
Houston Texans
On January 6, 2016, the Houston Texans signed Still to a reserve future contract. He was placed on injured reserve on October 5, 2016.
New York Jets
On August 4, 2017, Still signed with the New York Jets. He was waived on August 28, 2017. On December 23, 2017, Still announced his retirement from the NFL.
Personal life
In June 2014, his daughter, Leah Sari Still, was diagnosed with Neuroblastomastage 4 cancer. Still put his football career on hiatus saying: "she's fighting for her life. Sports is not more important than me being there while my daughter is fighting for her life." Since the June 2, 2014 diagnosis, Still spent the next three weeks sleeping next to his daughter at the hospital despite his own recent back surgery. In support of his daughter, Still shaved his head bald and has said that he will grow back his hair only when Leah's does. The Bengals demonstrated their loyalty even further by permitting Devon Still's jersey to be sold in order to raise awareness for pediatric cancer research and the Cincinnati Children's Hospital. $400,000 sales were made in four days. At the end of September, it was reported that Still's jersey donation sales neared $1 million. The New Orleans Saintshead coach, Sean Payton bought 100 jerseys and distributed them to the local Boys & Girls Club and the Cincinnati Children's Hospital. On September 25, 2014, before driving Leah to the Children's Hospital of Philadelphia for cancer surgery, Still posted a video to his Instagram account, which went viral. Still later tweeted that the tumor and lymph nodes were removed. On October 5, 2014, during a game with the New England Patriots at Gillette Stadium in Foxboro, Massachusetts, a music video was shown on the stadium's video screen featuring Still's daughter. The Patriots cheerleaders also donned copies of Still's' jersey to show support. It was further reported that Patriots owner Robert Kraft was donating $25,000 to Cincinnati Children's Hospital and Medical Center in Leah's name. On March 18, 2015, Still announced that Leah had undergone surgery to get the tumor out, and that she was now cancer-free. On July 15, 2015, at the ESPY awards, Devon and Leah Still received the Jimmy V Award for their determination and perseverance in the face of cancer. In November 2015, Still announced Leah was in remission with no signs of cancer. In January 2016, Still announced that Leah remained cancer-free and that she had "really beat cancer." Still's cousins, Art Still and Levon Kirkland, have also played in the NFL.
