A former NFL running back smacked his 11-year-old daughter during a scuffle earlier this month in Texas, authorities said.

Aaron Brown, 31, who was a member of the Cincinnati Bengals’ preseason roster in 2012, struck the pre-teen twice at her paternal grandmother’s Houston apartment on June 10, local station ABC 13 reported.

Brown, along with his wife, visited the apartment to meet with the girl and things got violent, according to court documents obtained by the station.

The grandmother told investigators she was in the living room while Brown met with his daughter in a bedroom, the outlet reported.

Suddenly she heard a loud commotion and went into the bedroom, where the dad and daughter were fighting.

She tried to step in between the two — but Brown reached around her and struck the girl twice on the right side of the head, the grandmother said.

A judge ordered Brown to stay away from his daughter as the case proceeds, the station reported.

Brown’s football career began at Texas Christian University back in 2005. His NFL debut came in 2009, when he was a sixth-round pick of the Detroit Lions.

Following his stint with the Bengals, he played one season with the Sacramento Mountain Lions of the United Football League.
