Some potential legal troubles for an NFL player.

FOX's Chris Hoenig reports:

Seattle Seahawks defensive back Brandon Browner is being investigated for an alleged assault.

Pomona, California police say the 31-year-old is accused of punching his girlfriend's father, who went to Browner's house on Tuesday after Browner and his girlfriend argued on the phone. The 59-year-old father reportedly fell and hurt his thumb, but refused medical attention.

Browner left before police arrived. Detectives are investigating and will decide whether to send the case to prosecutors.
