SAN DIEGO (AP) Running back Ronnie Brown is back with the San Diego Chargers, his unemployment in the NFL having lasted just one week.
Brown calls it a ''no-brainer'' because he's familiar with the system, having played for the Chargers in 2012 and 2013.
Brown was released last week by the Houston Texans. He says the Denver Broncos first contacted his agent on Monday evening, followed by the Chargers.
The Chargers need running back depth after Donald Brown sustained a concussion in Sunday's 31-0 victory against the New York Jets.
Also Wednesday, center Rich Ohrnberger practiced for the first time in three weeks, although he was limited due to a back injury that forced him to miss the last two games.
The Chargers (4-1) visit AFC West rival Oakland (0-4) on Sunday.
