The 49ers signed a familiar face, Bruce Davis, to the practice squad on Tuesday. The outside linebacker had a brief stint on the practice squad for the team in 2010. Davis (6-3, 252) played at UCLA and was a third-round draft choice by the Steelers in 2008. He's also spent time on the practice squads of Bengals and Patriots and has been on the active rosters of the Raiders and Steelers.
Davis fills the spot left open when receiver Joe Hastings was promoted to the 49ers' active roster.
