The San Francisco 49ers signed another linebacker, adding former New York Jets backup Nick Bellore to the roster on a two-year deal. Bellore has played in every game for the Jets over the past four seasons. He has 61 tackles during that span, primarily covering kicks. The 49ers had two linebackers, Patrick Willis and Chris Borland, retired this offseason. They signed linebacker Desmond Bishop this week.
