Seattle Seahawks cornerback Brandon Browner will not be charged after an allegation that he punched his girlfriend's father at a Southern California home.

The Los Angeles County district attorney's office told the Seattle Times on Wednesday that there would be no charges filed against the 32-year-old, but did not elaborate on the investigation.

Police in Pomona said that on July 5 officers were sent to a home where Browner's girlfriend, the mother of his two children, was living. Browner lives in the same neighbourhood.

The woman's father said that after the couple had argued he and Browner got into a dispute and Browner punched him, forcing him to fall down and hurt his thumb.

Browner's agent declined comment at the time and could not immediately be reached on Wednesday.
