The 49ers will sign inside linebacker Desmond Bishop, the Sacramento Bee reports.
Bishop joined the 49ers last December and recorded two tackles in two games. He emerged as a starter with the Packers in 2010 and racked up more than 100 tackles for two straight seasons before missing the 2012 season and becoming a free agent. He could win significant playing time in the 49ers' base set after the retirements of Patrick Willis and Chris Borland.
