Prosecutors won't charge Junior Seau

SAN DIEGO -- Prosecutors in San Diego won't charge former NFL star Junior Seau after his live-in girlfriend alleged she was assaulted.

The San Diego County district attorney's office said Friday that it reached its decision after reviewing an investigation by Oceanside police. The office declined to elaborate in a brief statement.

The 41-year-old Seau was arrested early Monday on suspicion of domestic violence. Police said his 25-year-old girlfriend reported that she was assaulted during an argument.

The former standout linebacker for the San Diego Chargers quickly posted bail. A few hours later, his SUV plunged down a seaside cliff. Seau escaped serious injury.

Seau also played for the Miami Dolphins and New England Patriots before retiring in 2009.
