The mother of the cancer-stricken daughter of Cincinnati Bengals defensive linemen Devon Still has filed suit charging he is four-months delinquent on child support payments to his four-year-old daughter.

Still’s story has captured many of the hearts and much of the attention NFL Nation and beyond this season as he’s fought to preserve the NFL career he’s stated allows him to afford the treatments his daughter needs for the rate form of pediatric cancer known as neuroblastoma she suffers from.

But according to the New York Daily News, Channing Smythe has now hired civil rights attorney Gloria Allred to represent her in her filing. On Tuesday, Allred delivered a letter to NFL offices asking league officials to investigate if Still is in violation of the league’s Personal Conduct Policy based on his delinquent standing.

“I don’t consider him a deadbeat dad,” Smythe told The News. “I know he loves and cares for his daughter and is there for her. I just need him to help me financially.”

Smythe further alleges her daughter’s condition prevents her from working because she requires full-time care. She adds the family would be homeless if a friend of her mother had not allowed them to reside with her. Smythe also alleges she has was forced to begin receiving food stamps in July to feed herself and her daughter.

Allred admits Still has paid some child support his daughter out of the $570,000 he is expected to earn this season, but recently called her client to inform her he would no longer be making the payments and “would see her in court.”

Still reportedly travels every week from Cincinnati to Delaware to see his daughter. The Bengals were widely saluted by fans after they announced they would be keeping Still on the team’s practice squad so he would be eligible for NFL medical benefits, aiding him to afford the treatments needed by his daughter. In September, he was promoted to the 53-man NFL roster.

The Bengals also recently presented Still with a $1.3 million check from money generated from the sale of his No. 75 jersey. The money was earmarked for pediatric cancer research wing of the Cincinnati’s Children’s Hospital.
