Seahawks' Brandon Browner being investigated for alleged assault

Police in Pomona, California, are investigating an alleged assault by Seattle Seahawks cornerback Brandon Browner on the father of his girlfriend Tuesday night.

Watch Commander Lt. Ronald McDonald confirmed to ESPN that police responded to a call at 8 p.m. PT after an argument between Browner and his girlfriend spilled onto the driveway. The father of Browner's girlfriend went to the house, where he and Browner had an altercation in the driveway, according to police. Browner's girlfriend's father, who is 59, told police he was assaulted once and fell to the ground, where he injured his thumb.

McDonald said the girlfriend's father did not seek medical attention so police don't currently know the extent of his injuries. Police said he visited with his personal doctor.

Police have not spoken with Browner, McDonald said, who left the scene before police arrived. Detectives are reviewing the case; McDonald expects a decision to be made either Wednesday or Thursday whether to issue a warrant for Browner's arrest.

Browner, who grew up in Sylmar, California, located about 50 miles northwest of Pomona, re-signed with the Seahawks this season to play a hybrid linebacker/safety role.

Browner, 31, began his NFL career in 2005 with the Denver Broncos as an undrafted free agent, but he suffered a season-ending injury in preseason and was placed on injured reserve. He was cut the following year and landed in the CFL from 2006 to 2010. He signed with the Seahawks in 2011, spending three seasons in Seattle before signing with the New England Patriots in 2014. A year later, he played for New Orleans before returning to Seattle in March.
